Why we need Aviation Legislation?

Aircraft is an international vehicle and Transportation of passengers and goods with

aircraft does not confine itself to national borders. Inherent in aviation, is certain amount of risk and danger Rules and regulations were worked out for the following reasons:

Protection of people on the ground Protection of paying passengers and cargo Protection of cockpit and cabin crews Standardization of activities within the civil aviation industry worldwide To ensure safe, airworthy and reliable civil aircraft operation

What is Aviation Legislation?

“Aviation Legislation” is a term generally used to define the process through which Laws (or Regulations) relating to all areas of civil aviation industry are brought into force”

In Pakistan, Rules, Regulations and statutes are brought into force through Civil Aviation Rules/Air Navigation Orders, Airworthiness Notices and policy Letters, issued from time to time by PCAA.

Regulatory Framework Role of ICAO

In 1889, First Int. Conference was held in Paris to establish some generally accepted

form of Air Law No real progress till First World War In 1914 UK, Aeronautical Inspection Directorate (AID) was formed to ensure high

standards of inspection throughout Aircraft industry In 1918 UK, Air Ministry was formed and control of AID was transferred to this

Ministry In 1919, International Convention for Aerial Navigation (ICAN) took place in Paris,

which made a number of definitions and classifications like Private & state Aircraft In 1919, Air operator on realizing international cooperation established International

Air Traffic Association In 1929, International Conference on private air law was held commonly known as

Warsaw Convention overcoming the difficulties of selecting the law of which nation would be applicable in a given set of circumstances

In November 1944, 52 nations sent representative to an International Civil aviation convention at Chicago. In this convention principles and arrangements were setup on International air rights. Pending ratification of the convention by 26 states, the Provisional International Civil aviation Organization was established. It functioned from 6 June 1945 until 4 April 1947.

In 1945, International Air Transport Association (IATA) was created by an act of Canadian Parliament and replaces International Air Traffic Association

On 4th April 1947, International Civil aviation Organization (ICAO) was established by the Chicago convention. In October of the same year, ICAO became a specialized agency of the United Nations linked to the Economic and Social Council (ECOSOC).

Chicago convention is the constitution of ICAO. Currently there are 190 contracting states PCAA is a member of ICAO

Aims and Objectives of ICAO

Safe and orderly development of International Civil Aviation Aircraft design and operation for peaceful purposes Development of air navigation facilities Prevent economic waste caused by unreasonable competition Give a fair opportunity to every contracting state to operate international airline

Role of EASA

In 1970 work started on Joint Aviation Authorities (JAA) with the objectives to produce common certification requirements for large airplanes and engines to meet European Industry requirement (like Airbus); headquarter in Hoofddorp Netherland.

In 1987 work of JAA was extended to operations, maintenance, licensing and certification/design standards for all classes of aircraft

Since 1992 JAA codes are referenced in the European Community as Regulation on Harmonized Technical standards and have become law in the EC states

In 2002, EASA was created; controlled by the European commission; headquarter in Köln (Germany)

In 2003, EASA signed the Cyprus Arrangement and became operational for certification of aircraft, engines, parts and appliances and continued airworthiness

In December 2003, First EASA type certificate was delivered EASA is NOT an ICAO contracting state Member states are known as ICAO Contracting States

EASA Regulatory Structure: EASA Parts: Acceptable Means of Compliance (AMC): An AMC is a means or several alternative means to satisfy a requirement Guidance Material (GM): Published by EASA helps in the understanding of a requirement

The Relationship Between EASA and Other Aviation Authorities

EASA works closely with representatives of other organisations to ensure that the agency takes their views into account:

• Interested parties in industry, which are subject to rules drafted by EASA, are key to ensuring the success of civil aviation safety standards by assisting in the drafting and correct application of European Community and EASA rules;

• European aviation authorities perform a critical role in assisting EASA with the performance of its core rulemaking, certification and standardisation functions;

• International aviation organisations such as the Joint Aviation Authorities, Eurocontrol and the International Civil Aviation Organisation work together with EASA to promote international civil aviation standards;

• International aviation authorities such as the Federal Aviation Administration, Transport Canada, DAC/CTA (Brazil) and the Interstate Aviation Committee (Russia) work with EASA to ensure compliance with international standards and to facilitate trade in aeronautical products.

• Accident investigation bodies issue safety recommendations and analysis that guide the agency’s safety strategy.

Page 12: Aviation Legislation for Pakistani Aircraft Engineers

The Relationship between Part-66, Part-147 and Part-145

Under the European Aviation Safety Agency (EASA) regulation (EC) 1592/2002 it is a legal requirement throughout the member states of the European Union (EU) for aircraft to be maintained by organizations, which have been approved to do so by EASA and the approval, has been issued and is being supervised on its behalf by the Competent Authority in each member state and by EASA itself in non-member states. In the case of the UK the competent authority is the Civil Aviation Authority (CAA). The approval is issued in accordance with Implementing Regulations Part-145 (IR Part-145). As a consequence of this requirement, Certifying Maintenance Engineers and Mechanics who are employed within these maintenance organizations are required, in the first instance to be approved to a suitable standard based on education, training and experience. On satisfying the basic requirements, Certifying Maintenance Engineers and Mechanics are granted a licence by the relevant competent authority in accordance with Implementing Regulations Part-66 (IR Part-66). As they accumulate experience and undertake aircraft and equipment type and task training then this is reflected on their individual licenses and in the scope of work, which they are approved to carry out. In order to obtain the elements of basic training necessary for the granting of an IR Part-66 licence and to take the necessary examinations, which provide the evidence of conformity for the issue of a Part-66 licence, organizations have been set up in accordance with Implementing Regulations Part-147 (IR Part-147) these organizations are approved to provide the basic training, conversion of license training and aircraft and equipment type training depending on the specification of each IR Part-147 training organisation approval.

10.5 Aircraft Certification Level a) General – A B1 B2 Certification rules: such as IR PART–23/25/27/29; - 1 1 Type Certification; Supplemental Type Certification; Part–21 Design/Production Organisation Approvals.

Page 32: Aviation Legislation for Pakistani Aircraft Engineers

European Aviation Certification Standards (EACS or CS)

EACS 23/25/27/29 are based on the equivalent JAR requirements. An important element of this development has been the harmonization with the corresponding United States legislation FAR-25. The above referenced information is categorized as follows:

CS-23 Certification specification for Airworthiness of Normal, Utility, Aerobatic, and Commuter category aeroplanes.

CS-25 Certification specification for Airworthiness of Large Aeroplanes.

CS-27 Certification specification for Airworthiness of Small Rotorcraft.

CS-29 Certification specification for Airworthiness of Large Rotorcraft.

The content f the standards is generally divided into the following topics PERFORMANCES: (e.g. climb gradients one engine inoperative) and

handling qualities (e.g. static and dynamic stability, control force, etc.).

STRUCTURE: (e.g. gust envelopes, maneuvers envelope, fatigue requirements, etc.).

DESIGN AND CONSTRUCTION: (e.g. emergency evacuation provisions, fire protection etc.).

POWERPLANT INSTALLATION: (e.g. uncontained powerplant failure, fuel and oil system requirements, etc.).

SYSTEMS AND EQUIPMENT: (e.g. systems safety analyses: requirements for electrical, hydraulic and pneumatic systems: required equipment for flight and navigation, etc.).

MANUALS AND LIMITATIONS: (e.g. speed limitations, flight manual, continued airworthiness manual, etc.).

The above information has been extracted from the Certification Standard Explanatory notes. Additional information contained in these notes includes the exceptions applying to the use of units other than SI units within the EU. In aviation common use is made of the Knot, Nautical mile and foot; this is accepted and these units SHOULD NOT be converted to SI units.

Page 33: Aviation Legislation for Pakistani Aircraft Engineers

TYPE CERTIFICATION Before the production of Aircraft, Engines or Propellers the manufacturer needs a Type certificate from his Regulatory body. The authority will only accept an application for a type certificate provided he holds an appropriate Design Organization Approval (under JAR 21 subpart JA). In Europe, the Type certificates are issued by National Aviation Authorities in accordance with EASA regulations on behalf of the Agency when products show compliance with the requirements of EASA, i.e. aircraft manufacturers have demonstrated compliance with CS 23, 25, 27 or 29. The applicant (usually the manufacturer) will be issued with the type certificate; he now becomes the Type Certificate Holder and assumes responsibilities with regard to continuing support of products throughout their service. Type certificate is considered to include the type design, the operating limitations, the type certificate data sheet; the applicable requirements with which the authority records compliance and any other conditions or limitations prescribed for the product in the applicable requirements. One responsibility for the type certificate holder is to keep a register of all known users of the product and to communicate all new and updated airworthiness data to them. Further to this he must produce maintenance and overhaul manuals, illustrated parts catalogues etc. and provide a full range of product support facilities to ensure continued airworthiness of the items manufactured to the Type Certificate. An application for type-certification of large aeroplanes and large rotorcraft shall be effective for five years and an application for any other type-certificate shall be effective for three years, unless an applicant shows at the time of application that its product requires a longer period of time for design, development, and testing, and the Agency approves a longer period. Supplemental Type Certificate A Supplemental Type Certificate (STC) is a document issued by the Federal Aviation Administration (Manufacturer Regulatory Body) approving a product (aircraft, engine, or propeller) modification. The STC defines the product design change, states how the modification affects the existing type design, and lists serial number effectivity. It also identifies the certification basis listing specific regulatory compliance for the design change. Information contained in the certification basis is helpful for those applicants proposing subsequent product modifications and evaluating certification basis compatibility with other STC modifications.

Page 34: Aviation Legislation for Pakistani Aircraft Engineers

Part–21 Design/Production Organization Approvals

Aircraft Noise Certificate

ICAO Annex 16 Environmental Protection Vol.-I “Aircraft Noise” PCAA AWNOT-62 “Aircraft Noise Certificate”

Page 48: Aviation Legislation for Pakistani Aircraft Engineers

The Sixteenth Session of the ICAO Assembly, Buenos Aires, September 1968, adopted the following Resolution: A16-3: Aircraft Noise in the Vicinity of Airports

Whereas the problem of aircraft noise is so serious in the vicinity of many of the world’s airports that public reaction is mounting to a degree that gives cause for great concern and requires urgent solution;

Whereas the noise that concerns the public and civil aviation today is being caused by increase in traffic of existing aircraft;

Whereas the introduction of future aircraft types could increase and aggravate this noise unless action is taken to alleviate the situation;

Whereas the Fifth Air Navigation Conference of ICAO held in Montreal in November 1967 made certain recommendations,based on the principal conclusions of the International Conference on the Reduction of Noise and Disturbance Caused by Civil Aircraft (“The London Noise Conference”) held in London in November 1966, with the object of reaching international solutions to the problem through the machinery of ICAO;

(Part II. Aircraft Noise Certification Chapter 1.4) The documents attesting noise certification for an aircraft shall provide at least the following information: a) State of Registry; nationality and registration marks; b) Manufacturer’s serial number; c) Manufacturer’s type and model designation; engine type/model; propeller type/model (if applicable); d) Statement of any additional modifications incorporated for the purpose of compliance with the applicable noise certification Standards; e) The maximum mass at which compliance with the applicable noise certification Standards has been demonstrated. Only one maximum take-off and landing mass pair shall be certificated for each individual aircraft; (f) The average noise level(s) at the reference point(s) for which compliance with the applicable Standard has been demonstrated to the satisfaction of the certificating authority; g) The chapter of Annex 16, Volume I, according to which the aircraft was certificated; and h) The height above the runway at which thrust/power is reduced following full thrust/power take-off. The information required under 1.4 b) through h) shall be included in the flight manual. Noise evaluation measure

The noise evaluation measure shall be the effective perceived noise level in EPNdB

Maximum noise levels The maximum noise levels of aeroplanes, when determined in accordance with the noise evaluation method, shall not exceed the following: a) At lateral and approach noise measurement points: 108 EPNdB for aeroplanes with maximum certificated take-off mass of 272 000 kg or over, decreasing linearly with the logarithm of the mass at the rate of 2 EPNdB per halving of the mass down to 102 EPNdB at 34 000 kg, after which the limit remains constant; b) At flyover noise measurement point: 108 EPNdB for aeroplanes with maximum certificated take-off mass of 272 000 kg or over, decreasing linearly with the logarithm of the

Page 49: Aviation Legislation for Pakistani Aircraft Engineers

mass at the rate of 5 EPNdB per halving of the mass down to 93 EPNdB at 34 000 kg, after which the limit remains constant. Aircraft Noise certificate is also a requirement of JAR–OPS 1.125 “Documents to be carried” Noise Certificate (Ref. JAR-36- 120)

• must be accessible and stored with other airworthiness certificates • shall not exceed the noise levels specified in JAR-36.140 at the following points on

level terrain: Lateral reference measurement point: the point on a line parallel to and 450 m

from the runway centre line, or extended centre line, where the noise level after lift-off is at a maximum during take-off

Flyover reference noise measurement point: the point on the extended centre-line of the runway at a distance of 6.5 km from the start-of-roll

Approach reference noise measurement point: the point on the ground, on the extended centre-line of the runway 2000 m from the threshold. On level ground this corresponds to a position 120 m (394 ft) vertically below the 3"- descent path originating at a point on the runway 300 m beyond the threshold

Page 50: Aviation Legislation for Pakistani Aircraft Engineers

Weight Schedule (JAR-OPS1.605)

An operator shall specify in the operations Manual the principles and methods involved in the loading and in the mass and balance

system that meet the requirements of JAR-OPS 1.605 Each weight change has to be recorded and registered in the weight and balance sheet

of the aircraft A scheduled aircraft weighing has to be established for every flight a weight

calculation (load sheet) must be performed and signed by the pilot An operator

shall ensure that during any phase of operation, the loading, mass and centre of gravity of the aeroplane remains within the limitations

must establish the mass and the centre of gravity of any aeroplane by actual weighing before first service

must establish the mass of the traffic load must determine the mass of the fuel load by using the actual density or, if not known, the density calculated

Re-Weighing of Aircraft

Re-weighing of aircraft at the time of renewal of the Certificate of Airworthiness will be dependent on the date of the last weighing, and on the history of the aircraft. NOTE: Aircraft are normally weighed when all manufacturing processes are completed.

Aircraft of more than 5700 kg MTOM must be re-weighed within two years after the date of manufacture. Subsequent check weighing must be carried out at intervals not exceeding five years and at such other times as the CAA may require. Aircraft of 5700 kg MTOM or less must be re-weighed at such times as the CAA may require. The CAA must be consulted if there is any doubt as to whether the aircraft ought to be re-weighed. When re-weighing is necessary, an amended Weight and Centre-of-Gravity Schedule, or its equivalent, must be prepared. At the time of a re-weighing or when a revised Weight and Centre-of-Gravity Schedule is raised following the addition, removal or relocation of equipment, a copy of the Weight and Centre-of-Gravity Schedule must be retained by the Approved Organisation and made available to the CAA upon request. NOTE: For an aircraft operated by a JAR-OPS Operator, weighing requirements must be

determined in accordance with SUBPART J OF JAR-OPS 1 OR JAR-OPS 3 as appropriate.

15- AIRWORTHINESS DIRECTIVES Introduction Over the life of aeronautical products, defects affecting airworthiness are discovered. These result from design conditions not foreseen in the original Product Certification or manufacturing deficiencies. Many become evident only after years of in-service operation and are completely unforeseen. Structural fatigue or corrosion are examples. FAR/JAR 39 forms the basis of the procedures. Definition The Airworthiness Directive (AD) system is the medium for correction for any condition that causes the product to be out of conformity to the Approved Design Standards. An AD identifies the disparity, defines its particulars, and establishes limitations for inspection, repair, or alteration under which the product may continue to be operated. They are issued by the National Aviation Authority from either the manufacturer’s or the airline’s country. Airworthiness Directives effectively alter the original certification of the product. Thus, for example an AD against a Type Certificated product becomes a part of the Type Certificate. The Airworthiness Directives may also be raised due to change in aviation legislations e.g. mandating of TCAS and EGPWS. Distribution They are distributed

i) telegraphically to owners and operators ii) Organisations such as IATA, ATA etc. iii) Foreign Airworthiness Authorities

Their availability can be checked through

i) FAA ‘Summary of Airworthiness Directives’ ii) CAA (UK) ‘Mandatory Aircraft Modification and Inspection Summary

(MAMIS)’ iii) CAA (UK) ‘Foreign Airworthiness Directives’

These summaries are used to check any outstanding ADs against a given type of design and hence the airline and the operator would not be excused for missing any ADs. Contents of an Airworthiness Directive Generally the Airworthiness Directive is made up of several parts:

i) AD title ii) Applicability iii) Required compliance action iv) Effective dates v) Compliance time

We will proceed to detail the contents

Page 54: Aviation Legislation for Pakistani Aircraft Engineers

Applicability of ADs An AD contains an applicability statement specifying the product to which it applies. It applies to the make and model set forth in this statement, regardless of the classification of the product or category of the Airworthiness Certificate issued for an aircraft. it applies to each product identified in the statement, regardless of whether it has been modified, altered, or repaired in the subject areas. The presence of any alteration or repair does not remove the product from applicability. Type Certificate and Airworthiness Certification information is used to identify the product affected. Applicability may be defined by specifying serial numbers or manufacturer's line numbers, part numbers, or other identification. When there is no reference to serial numbers, all serial numbers are affected. Effective dates The effective date of the AD or an amendment is be found in the last sentence of the body of each AD. For example, "This amendment becomes effective on July 10, 1995." Similarly, the revision date for an emergency AD distributed by telegram or priority mail is the date it was issued. For example, "Priority Letter AD 95-11-09, issued May 25, 1995, becomes effective upon receipt." The "clock" tracking compliance starts with the effective date. Compliance time Compliance with an AD is mandatory. No person may operate' a product to which an AD applies, except in accordance with the conditions of the AD. An airplane that has not had an effective AD accomplished within specified limits is out of conformity and is thus not airworthy. This is consistent with the definition of airworthiness discussed before. Compliance time is stated in various ways. Typical compliance statements include; "Prior to further flight, inspect..." "Compliance is required within the next 50 hours time in service after the effective date of this AD..." 'Within the next 10 landings after the effective date of this AD... " 'Within 50 cycles...” to which cycle refers to the complete aircraft / components operating cycles. "Within 12 months after the effective date of this AD..." No person may operate an affected product after expiration of the stated compliance time. In some instances, an AD may authorize operation after the compliance date has passed, if a special flight permit is obtained. These are granted only when the AD specifically permits it. Recurring/periodic ADs In order to provide for flexibility in administering compliance requirements, an AD should provide for adjustment of repetitive inspection intervals to coincide with inspections required by approved maintenance program inspections. Any conditions and approval requirements under which adjustments may be allowed are stated in the AD. If the AD does not contain such provisions, adjustments are usually not permitted. However, amendment, modification, or adjustment of the terms of the AD may be requested.

Page 55: Aviation Legislation for Pakistani Aircraft Engineers

Alternative or equivalent means of compliance Many ADs indicate the acceptability of one or more alternative methods of compliance. Any alternative method of compliance or adjustment of compliance time other than that listed in the AD must be substantiated to and approved by the certifying Airworthiness Authority before it may be used. The alternative method may address either no action, if the current configuration eliminates the unsafe condition, or different actions necessary to address the unsafe condition. It may be stated in the AD itself e.g. an extra repetitive inspection in place of a mandatory modification. Reference to Manufacturer's Service Bulletins in ADs Manufacturer's Service Bulletins are normally not related to airworthiness. Incorporation of them is, therefore, not mandatory. However, when a manufacturer's Service Bulletin is incorporated, by reference, into the Airworthiness Directive accomplishment instructions the bulletin becomes mandatory. Thus any change in the details of the bulletin constitutes alternative means of accomplishment. Changes, therefore, must be approved.

DEFERRED MAINTANENCE MEL / CDL Introduction The regulations' traditionally specified that all installed aircraft equipment required by the airworthiness and operating regulations must be operative. However, experience indicated that, with varying levels of redundancy designed into airplanes, operation of every system or installed component was not necessary when the remaining operative equipment provided an acceptable level of safety. The Minimum Equipment List (MEL) is a document established by the operator and approved by National Authorities of the operator. Operator's MEL is developed on the base of manufacturer’s Master MEL (MMEL) and customised by the operator as a function of its own operational policies and national operational requirements. The Configuration Deviation List (CDL) is a document approved by the Airworthiness Authority having certified the aircraft. The CDL is included in the Aeroplane Flight Manual. These documents allow operations with certain items, systems, equipment, instruments or components inoperative or missing as it has been demonstrated that an acceptable level of safety is maintained by appropriate operating limitations, by the transfer of the function to another operating component(s) or by reference to other instruments or components providing the required information. MINIMUM EQUIPMENT LIST (MEL) Definition A MEL provides the means to release an airplane for flight with inoperative equipment. The intent is to permit operation for a limited period until repair or replacement of the defective equipment can be accomplished. It is, however, important that repair be accomplished at the earliest opportunity rather than continue operations indefinitely with inoperative equipment. Nothing in the concept disallows the authority of the pilot in command. The pilot may require that any item covered by the Minimum Equipment List be repaired before flight. Master Minimum Equipment Lists (MMEL) During type certification, the agreement between manufacturer and the Airworthiness Authorities formalizes the Minimum Equipment as the Master MEL or MMEL. The principal criteria used when adopting an MMEL item are that: i) An acceptable level of safety is assured after considering subsequent failure of the next

critical component within a system. ii) Any interrelationships between allowed inoperative items do not compromise safety. Once adopted, a list is subject to periodic revision. As operating experience is gained, revisions arise from needs from individual operators petitioning the Airworthiness Authority. There is no defined revision cycle. There is usually a separate list for each large airplane type; for example, the MMEL for the 737 addresses all model variants of that type design. Small airplanes are covered by a generic master list.

Page 58: Aviation Legislation for Pakistani Aircraft Engineers
Page 59: Aviation Legislation for Pakistani Aircraft Engineers

Operator Minimum Equipment Lists (MEL) MMELs are not intended for operating use. Rather they act as the source document from which an individual operator's MEL is developed. An individual operator's MEL when appropriately authorized permits operation with inoperative equipment for those aircraft listed in his Operations Specifications. The Operator’s MEL is developed to satisfy

i) MMEL ii) Manufacturer’s recommendations iii) Operator’s company Standards and Policies iv) Operator’s general company procedures v) Operator’s Flight Operations procedures vi) Operator’s Maintenance procedures.

Operator MELs will frequently differ in format and content from the MMEL but they cannot be less restrictive. Operators are responsible for exercising the necessary control to ensure that an acceptable level of safety is maintained. This includes a repair program embracing the parts, personnel, facilities, procedures, and schedules to ensure timely clearance of deferred items. Suitable conditions and limitations in the form of placards, maintenance procedures, crew operating procedures, and other restrictions that are necessary must be specified. In operating with multiple inoperative items, the interrelationships between those items and the effect on airplane operation and crew workload must also be considered. MEL Repair Interval As The MEL is not intended to provide for continued operation of an aircraft for an unlimited period of time. Repairs should be made as soon as possible within the time limit imposed by Rectification Intervals. Rectification Intervals (A, B, C, and D) have been introduced in accordance with definitions of JAR-MMEL/MEL Category A. Items in this category must be repaired within the interval stated in the operator's approved MEL. Category B. Items in this category must be repaired within 3 consecutive calendar days (72 hours), excluding the day the malfunction was recorded in the maintenance record (logbook). Category C. Items in this category must be repaired within 10 consecutive calendar days (240 hours), excluding the day the malfunction was recorded in the maintenance record (logbook). Category D. Items in this category are those which are in excess of regulatory requirements. They include items that may be installed, deactivated, or removed at the discretion of the operator. They may be added to the operator's MEL but are not required by the MMEL or are required only for a given type of operation. These must be repaired within 120 consecutive calendar days, excluding the day the malfunction was recorded in the maintenance record (logbook). Dispatch of the aircraft is not allowed after expiry of the Rectification Interval specified in the MEL unless the Rectification Interval is extended in accordance with the following: A one time extension of the applicable Rectification Interval B, C, or D, may be permitted for the same duration as that specified in the MEL provided:

Page 60: Aviation Legislation for Pakistani Aircraft Engineers

i) A description of specific duties and responsibilities for controlling extensions is established by the operator, and

ii) The Authority is notified within 10 days of any extension authorised. Approval of Operator MEL When reviewing the proposed MEL, the Airworthiness Authority will check for the following:

i) Nothing is contained in the MEL that is less restrictive than the MMEL. ii) Nothing contradicts the FAA approved Airplane Flight Manual iii) Nothing violates any limitations and conditions stipulated by ADs issued

against the aircraft iv) Operations (0) and maintenance (M) procedures required by the MMEL are

adequate v) A defined management control process for administration of the MEL

Deferral Procedures Once it has been determined that an item is deferrable, a decision is made to defer or fix it. This normally involves, at the minimum, station maintenance personnel and the pilot in command. However, in many instances flight dispatch, maintenance engineering, and a central maintenance control or quality control organization will be a party to the decision. Some airlines designate, in the body of their MEL, specific individuals or organizations that have deferral authority for each item listed in their MEL. After the decision is made to defer, specific actions will be taken by various organizations. Station maintenance personnel will:

Properly secure the deferred item in accordance with company procedures. Appropriately, placard the cockpit. Clear the aircraft log by transcribing the item from the airplane log to a deferred maintenance log or its equivalent. The deferred log is carried aboard the airplane and is available to the pilot in command. Notify the record-keeping function within the airline so that the necessary bookkeeping will take place, thus ensuring that the item is properly tracked and scheduled for later repair within allowable time limits. Notify dispatch and/or the pilot in command that the item is deferred. Notify any other organizations within maintenance that may be affected by the deferral; for example, main base stores, line station maintenance, central maintenance control. Dispatch and/or the pilot in command shall, as appropriate, Observe any special limitations or modified operating procedures attendant to the deferred item. Notify other operations organizations and line stations affected by the deferral.

Maintenance control or other appropriate organization charged with tracking deferred items and scheduling will take appropriate action to clear the item from the deferred log within the allowed time for deferral.

CONFIGURATION DEVIATION LIST (CDL) Introduction During the course of operation, certain secondary airframe or engine parts may be missing from the aircraft. Normally these will be access doors, fairings and non-structural parts. Absence of these parts does not adversely affect the basic aircraft handling and performance. As such they are not considered as airworthiness items Definition Configuration Deviation List (CDL) is a means of releasing the aircraft with items missing from aircraft standard design configuration. Determination of items is done during type certification itself i.e. they have been flight tested during certification. The CDL is a part of the Approved Aircraft Manual. Handling CDL items Although the concept of Rectification Interval does not exist for the CDL, all CDL items are not allowed to be left unrepaired for an unlimited period of time as stated in the Flight Manual. However, a specific time limit is required in the dispatch condition itself for some items. Decision for repair is under the operator responsibility. It is company policy that every effort be made to maintain 100 % serviceability with rectification being initiated at the first practical opportunity. An aircraft must not be dispatched with multiple MEL/CDL items inoperative without the Commander having first determined that any interface or interrelationship between inoperative systems or components will not result in a degradation in the level of safety and/or undue increase in crew workload. In case of defect, engineering personnel will certify in the Technical Log adjacent to the appropriate defect the MEL / CDL subject title, system and item number together with any operational limitations. When applicable, operational flight plan, take off and landing performance and fuel requirement penalties must be taken into account due to inoperative equipment or component. When a CDL item is rectified, engineering personnel should make an entry in the Technical Log identifying the item and details of the rectification, including a statement that the CDL item has been removed.

MAINTENANCE CHECKS Introduction With the MRB Report finalised, the maintenance programme for the aircraft is approved by the certifying Airworthiness Authority. However MRB reports on its own cannot be used directly. As MRB only define the basic type configuration, it will not cover buyer furnished items such as customised avionics package and in-flight entertainment systems. Another document is needed before a complete maintenance programme can be derived. Maintenance Planning Document The aircraft manufacturers produce the Maintenance Planning Document (MPD). It supplements the MRB and is advisory. It includes buyer furnished equipment and is customised to suit the airline’s fleet. Some manufacturers will also include information from Service Bulletins, Service Letters and other sources. A scheduled maintenance program is constructed from the MRB report and the materials contained in the MPD. Included in the MPD are:

i) Maintenance labour-hours estimates for tasks ii) Facilities and tooling recommendations iii) Recommended optional maintenance tasks iv) Administrative process and planning information, including packaging

methods The airline builds its maintenance programme around the MPD. Task cards The smallest unit in a maintenance programme is a task. These individual tasks are printed on individual card for action by the maintenance crew. Task cards translate individual inspections, checks, or other maintenance work into specific task instructions to be followed by individual certifying staff when performing work. They provide space for individual sign-off by the certifying staff accomplishing the work and the appropriate inspector sign-off for Duplicate Inspection Items. They are a part of the aircraft maintenance record. They are divided into two categories, routine and non-routine. Routine cards are those tasks defined by the inspection program. They come from the scheduled maintenance program. Non-routine discrepancy cards document discrepancies discovered during the conduct of a given inspection or other maintenance activity. They are ad hoc word instructions addressing the specific repair task to be accomplished. Deficiencies discovered during flight are not recorded on non-routine cards. Rather the pilot in the aircraft technical logbook or the cabin crew in the cabin log enters them.

CERTIFICATE OF MAINTENANCE REVIEW

Introduction

An aircraft registered in the Pakistan, in respect of which a Certificate of Airworthiness in the Transport Category (Passenger), Transport Category (Cargo) or Aerial Work Category and Private is in force, shall be subject to a maintenance review at intervals specified in the Approved Maintenance Schedule or the relevant Approval Document of the Maintenance Schedule, as appropriate. At the completion of a review, a Certificate of Maintenance Review shall be issued. General Rules The Signatory shall only issue a Certificate of Maintenance Review when satisfied, at the time of the review, that the following aspects of maintenance have been carried out: i) All maintenance specified in the Approved Maintenance Schedule has been carried out

within the prescribed time period and any extension to limiting periods is in accordance with PCAA approved procedures.

ii) All modifications and inspections deemed mandatory by the PCAA have been carried out within the prescribed time periods and any extension to limiting periods has been authorized by the PCAA. Due account must be taken of any repetitive inspections.

iii) All defects entered in the Technical Log have been rectified or deferred in accordance with PCAA Approved procedures.

iv) All Certificates of Release to Service required have been issued in accordance with the procedures of BCAR A6–7

The time intervals for the Certificate of Maintenance Review will be specified on a calendar ‘not exceed’ basis only and therefore, it is not necessarily intended to align with any check except for the renewal of the certificate of airworthiness. The issue of Certificate of Maintenance Review should not exceed 4 calendar **months for all aircraft type except for private category aircraft of less than 2730kg MTWA, which shall not exceed 1 year. A certificate of maintenance review shall be issued in duplicate. One copy of the most recently issued certificate shall be carried in the aircraft and the operator elsewhere than in the aircraft shall keep the other.

Page 66: Aviation Legislation for Pakistani Aircraft Engineers

TECHNICAL LOG

A technical log shall be maintained in respect of a Pakistan registered aircraft if in relation to such aircraft a certificate of airworthiness in either the transport or in the aerial work category is in force.

General Rules At the end of every flight by an aircraft, the commander of the aircraft shall enter—

(i) the times when the aircraft took off and landed; (ii) particulars of any defect which is known to him and which affects the airworthiness or

safe operation of the aircraft, or if no such defect is known to him, an entry to that effect shall be made; and

(iii) such other particulars in respect of the airworthiness or operation of the aircraft as the Director General may require,

in a technical log, or in the case of an aircraft of which the authorised maximum total weight does not exceed 2,730 kilogrammes and which in private or special category, in such other record as shall be approved by the Director General.

Upon the rectification of any defect which has been entered in a technical log a person issuing a certificate of release to service required in respect of that defect shall enter the certificate in the technical log in such a position as it will be readily identifiable with the defect to which it relates.

Basic Technical Log Requirements

ii) The original date of occurrence of the defect deferred; iii) Brief details of the defect; iv) A cross-reference for each deferred defect such that the action in respect of such deferred

defect can be readily identified on the sector record page.

Retention of Records The technical log shall be carried in the aircraft as required and copies of the entries shall be kept on the ground: A technical log or such other approved record required by PCAA shall be preserved by the operator of the aircraft to which it relates until a date two years after the aircraft has been destroyed or has been permanently withdrawn from use, or for such shorter period as the Director General may permit in a particular case. Adequate arrangements shall be made to extract information recorded in the Technical Log for use by the Maintenance Organization. DUPLICATE INSPECTION

Definitions Vital Point. Any point on an aircraft at which single mal-assembly could lead to catastrophe, i.e. result in loss of aircraft and/or in fatalities. Certain parts in an aircraft ’s structure or system (including controls and control systems) which are vital to the safety of the aircraft, are not only designed to achieve the appropriate high integrity but are also dependent upon specified maintenance actions to safeguard their integrity throughout the life of the aircraft. For such parts normal inspection procedures and techniques may not provide verification with a sufficiently high degree of confidence, and it will be necessary for two independent (duplicate) inspections to be carried out after initial assembly, or re-assembly following disconnection or adjustment

The vital points shall be identified and listed in the maintenance documents.

Control System. A system by which the flight path, attitude, or propulsive force of an aircraft is changed, including the flight, engine and propeller controls, the related system controls and the associated operating mechanisms. Duplicate Inspection. An inspection first made and certified by one qualified person and subsequently made and certified by a second qualified person.

Page 68: Aviation Legislation for Pakistani Aircraft Engineers

Procedures – General A duplicate inspection of all Vital Points/Control Systems in an aircraft shall be made after initial assembly and before a Certificate of Release to Service has been issued after overhaul, repair, replacement, modification or adjustment and, in any case, before the first flight.

The first and second inspections must take account of the full extent of the work undertaken and not simply the immediate area of disturbance. This is to ensure that distant or remote parts of the system that may have been affected by the disturbance are also subject to duplicate inspections.

Where work has been carried out on other systems for safety precautions, or to enhance accessibility, the need to carry out a duplicate inspection on these systems shall be considered. Persons who carry out and certify duplicate inspections are therefore required to undertake an independent review of the complete task, as detailed in the maintenance manual and by reference to worksheets used, including shift hand-over records, to assess the scope of the duplicate inspection(s)required. It may not be possible to inspect the complete Vital Point/Control System when assembled in the aircraft, due to routing the controls through conduits or boxed-in sections and the pre-sealing of various units. In these cases the persons certifying the duplicate inspection shall be satisfied that a duplicate inspection has been made previously on the units and covered sections and that the sealed units are acceptable for the particular use. Such tests as are necessary shall be completed to determine that these particular units and sections have full, free and correct directional movement.

Vital Points/Control Systems subject to duplicate inspection must not be disturbed or re-adjusted after the first certified inspection and the second part of the duplicate inspection must, as nearly as possible, follow immediately after the first part.

It is desirable that the inspections of a Control System are made as near as is practicable to the time of the intended flight and that the full extent of the disturbance is understood by both persons who carry out the duplicate inspections.

If a Vital Point/Control System is disturbed after completion of the duplicate inspection, that part that has been disturbed shall again be inspected in duplicate and a Certificate of Release to Service issued before the aircraft flies.

The duplicate inspection shall be the final operation to establish the integrity of the Vital Point/Control System when all the work has been completed and shall take into account all the relevant instructions and information contained in the associated technical data.

Inspections shall include an inspection to ensure that full, free and correct movement of the controls is obtained throughout the systems relative to the movements of the crew controls. An additional inspection shall be made, when all covers and fairings are finally secured, to ensure that full, free and correct movement of the controls is obtained.

Signatories Persons qualified to make the first and/or second part of a duplicate inspection are as follows:

i) Aircraft engineers appropriately licensed in Categories A, B,C,D and X. ii) Persons employed by Approved Organisations, who are appropriately authorized to make

such inspections and to certify the task itself in accordance with company procedures.

Page 69: Aviation Legislation for Pakistani Aircraft Engineers

iii) Should a minor adjustment of the Vital Point/Control System be necessary when the aircraft is away from base, the second part of the duplicate inspection may be completed by a pilot or flight engineer licensed for the type of aircraft concerned

MAINTANENCE, REPAIR AND OVERHAUL MANUAL

Introduction

Manuals containing information and recommendations necessary for the maintenance, overhaul and repair of aircraft, including engines and auxiliary power units, propellers, components, accessories, instruments, electrical and radio apparatus and their associated systems, and radio station fixed fittings, shall be provided by the constructor/manufacturer/Type Design Organisation to comply with the procedures outlined in this BCAR Chapter A5-3 for aircraft to be granted a Certificate of Airworthiness.

General Except as otherwise agreed by the PCAA, manuals shall be certificated and published under the authority of the appropriate Approved Organisation and shall accurately reflect the design and production standard of the item concerned

Manuals, published by an Approved Organisation, must bear a statement that they comply with BCAR A5-3. A copy of each certified manual must be lodged with the PCAA.

STATEMENT OF INITIAL CERTIFICATION signifies PCAA’s approval of the manuals.

Engine, auxiliary power unit and propeller constructors and manufacturers of other components shall provide the aircraft Type Design Organisation with certified manuals which relate to those of their products installed in the aircraft. In the case of approved products the certified manuals shall be provided by the manufacturer, or produced by the aircraft Type Design Organisation in collaboration with the manufacturer. All manuals shall be adequately illustrated and include such instructions and information considered necessary to meet the requirements of Continued Airworthiness. Manuals conforming with the Specification for Manufacturers ’ Technical Data – Air Transport Association of America – Specification No.100,would also be acceptable as a basis for compliance, subject to the inclusion of any variations from the Specifications which may be required by the DCA and which are defined to the Applicant. ATA Specification 100 ATA Specifications 100 has been adopted as a global standard with regards to Engineering Manuals Specifications. These standards has been adopted by both IATA and ICAO and followed by all aircraft and parts manufacturer. The intentions of the Specification are (1) To clarify the general requirements of the airline industry with reference to coverage and

preparation of technical data. (2) To provide an airline with all necessary data for the operation, maintenance, overhaul,

repair of aircraft, engines and equipment. (3) To permit maximum usage without the necessity of rewriting to meet individual airline

requirements. (4) To standardise manual layout, format of manuals (5) Specify Revisions Procedures for the issue of Service Bulletin

Page 70: Aviation Legislation for Pakistani Aircraft Engineers

The manual defined and described by ATA Specification 100 are as follows: Maintenance Manual, Overhaul Manual, Illustrated Parts Catalogue, Tool and Equipment lists, Wiring Diagram Manual, Service Bulletins, Structural Repair Manual, Weight and Balance Manual. The following list of systems, sub-systems and titles shows examples of the breakdown of a typical manual according to ATA 100. The major divisions are termed 'Group', each group being divided into chapters and allocated blocks of chapter numbers. Thus. GROUP CHAPTER NUMBERS Aircraft General 1 -19 Aircraft Systems 20-49 Structures 50-59 Propellers/Rotor 60-69 Power Plant 70-89 Each chapter is arranged alphabetically in a group and is divided into sections and then further sub-divided into designated subjects by a "dash number". EXAMPLE

ATA 24 – 21 – 8 24 21 8 Chapter Section Subject or System Sub-system Topics Electrical Power Main Generation Voltage Regulator

Page 71: Aviation Legislation for Pakistani Aircraft Engineers

The manuals are also required as a part of Instructions for Continued Airworthiness requirement of the Type Certificates/Supplementary Type Certificates of the aircraft. The Instructions for Continued Airworthiness will determine the required number of manuals required but the broad listing are as follows:

Maintenance Manuals (MM)

A manufacturer's maintenance manual is the primary reference tool for the LAE working on aircraft. Airframe maintenance manuals generally cover an aircraft and all of the equipment installed on it when it is in service. Powerplant maintenance manuals, on the other hand, cover areas of the engines that are not dealt with in the airframe manual. Maintenance manuals provide information on routine servicing, system descriptions and functions, handling procedures, and component removal and installation. In addition, these manuals contain basic repair procedures and troubleshooting guides for common malfunctions. Maintenance information presented in these manuals is considered acceptable data by the PCAA, and may be approved data for the purpose of major repairs and alterations.

Overhaul Manual Overhaul manuals contain information on the repair and rebuilding of components that can be removed from an aircraft. These manuals contain multiple illustrations showing how individual components are assembled as well as list individual part numbers.

Page 72: Aviation Legislation for Pakistani Aircraft Engineers

Illustrated Parts Catalogue (IPC) Parts catalogues show the location and part numbers of items installed on an aircraft. They contain detailed exploded views of all areas of an aircraft to assist the technician in locating parts. Approved parts are controlled here provided it is current and not superseded by mandatory instructions. Wiring Diagram Manual (WDM)

The majority of aircraft electrical systems and their components are illustrated in individual wiring manuals. Wiring manuals contain schematic diagrams to aid in electrical system troubleshooting. They also list part numbers and locations of electrical system components.

Structural Repair Manual (SRM)

For repair of serious damage, structural repair manuals are used. These manuals contain detailed information for repair of an aircraft's primary and secondary structure. The repairs described in a structural repair manual are developed by the manufacturer's engineering staff, and thus are usually considered approved data by the PCAA.

Service Bulletins (SB) and Service Notes

One way manufacturers communicate with aircraft owners and operators is through service bulletins and service notes. Service bulletins are issued to inform aircraft owners and technicians of possible design defects, modifications, servicing changes, or other information that may be useful in maintaining an aircraft or component. On occasion, service bulletins are made mandatory and are incorporated into airworthiness directives to correct an unsafe condition.

Page 73: Aviation Legislation for Pakistani Aircraft Engineers
Page 74: Aviation Legislation for Pakistani Aircraft Engineers

AIRCRAFT, ENGINE AND PROPELLER LOGBOOKS

Introduction

In addition to any other logbooks required by or under PCAA, the following logbooks shall be kept in respect of every Pakistan aircraft flying for the purpose of public transport: (a) an aircraft log-book; (b) a separate log-book in respect of each engine fitted in the aircraft; and (c) a separate log-book in respect of each variable pitch propeller fitted to the aircraft In the case of an aircraft having an authorised maximum total weight not exceeding 2,730 kilogrammes the logbooks shall be of a type approved by the Director General. General When all the relevant work has been carried out, a Certificate of Release to Service shall be entered in/attached to the appropriate logbook. Where it is more convenient, the required particulars may be entered in a separate record, but an entry shall be made in the appropriate logbook, containing a summary of the work carried out and a cross-reference to the document containing the Certificate of Release to Service. Full particulars of work done to incorporate modifications shall be entered in the appropriate logbook, quoting the reference number of the appropriate document, e.g. Certification of Compliance Document for a Major modification, Service Bulletin for a mandatory inspection.

EXTENDED TWIN ENGINE OPERATIONS (ETOPS)

Introduction

ETOPS (Extended Twin Operations) is defined by ICAO to describe the operation of twin-engined aircraft over a route that contains a point further than one hour's flying time, at the approved one engine inoperative cruise speed (under standard conditions and in still air), from an adequate airport. Regulations

ETOPS requirements are essentially the same for all the airworthiness authorities and are detailed in the following regulations: - FAA issued Advisory Circular (AC) 120-42A which provides the criteria for 75-, 120- and

180-minute operations, - the European Joint Airworthiness Authorities (JAA) developed the Advisory Material Joint

(AMJ) 120-42 with provisions for accelerated approval for 75-, 120- and 180-minute operations (currently published as Information Leaflet (IL) number 20).

PCAA regulations with regards to ETOPS are also derived from above. ETOPS Approval The approval process is summed thus - Manufacturer must obtain ETOPS Type Design Approval - The operator must obtain ETOPS Operational Approval ETOPS Type Design Approval It is the responsibility of the aircraft manufacturer to ensure that the aircraft's design satisfies the ETOPS regulations. Once the airworthiness authorities have agreed that the candidate aircraft engine combination meets the requirements of the applicable regulations, the authorities declare this aircraft type capable of flying ETOPS for a given maximum diversion time. The ETOPS capability of the aircraft-engine combination is declared in the following documents approved by the Airworthiness Authorities - Type Certification Data Sheet (TCDS), - Aircraft Flight Manual (AFM), - Configuration, Maintenance and Procedures Standards (CMP), - Master Minimum Equipment List (MMEL). The continuality of the ETOPS Type Design Approval is dependent on satisfactory global in-service experience of the said type. This is under the purview of the type certifying authority. For example, the FAA, for Boeing and other American aircraft and the JAA, for Airbus and other European aircraft. ETOPS Operational Approval An operator’s twin-engine aircraft can only operate ETOPS flight unless authorized by Operation Specification Approval (for both Maintenance and Flight Operations) issued by the local Airworthiness Authority, PCAA for Pakistan.

The operator has to prove that it has the appropriate experience with the considered airframe/engine combination and, that it is familiar with the considered area of ETOPS operation. ETOPS Operational Approval issued by PCAA does not refer only to the approval of the operator's flight operations organisation and procedures but, more broadly, to all of the following aspects: aircraft configuration, maintenance practices, ETOPS training and dispatch practices. On the satisfaction of the PCAA that the above conditions are met, these documents are amended:

iv) Crew Manual / Operation Manual v) Operator’s MEL vi) Company’s Engineering Manual

Specific manual for all company ETOPS-related engineering procedures is mandatory and this is the ETOPS Maintenance Manual. Upon satisfactory application, the PCAA will grant to the airline an Operational Approval to conduct ETOPS flight with a given maximum diversion time. This Operational Approval can be in the form of an approved Operations Specification containing the appropriate limitations. The ETOPS Operational Approval is for 75, 90, 120, 138, 180, and 207 minutes not exceeding the Type design approval for the aircraft itself. PCAA currently provides ETOPS operational approval on a route-to-route basis. Maximum permitted diversion time upon entry into service of airframe/engine combination is 120 minutes. The continuality of the ETOPS Operational Approval shall depend on the good In-Flight Shutdown (IFSD) rate for the operator’s ETOPS fleet. Any ETOPS-related incident must be highlighted to PCAA within 24 hours.

A non-ETOPS flight will be constrained by the shaded 60 min flight-time circles. A 120 min ETOPS flight-time circles would permit a direct routing.

ALL WEATHER OPERATIONS Introduction The term All Weather Operations is used to describe aircraft operations under all runaway visibility conditions with regards to takeoff, landing and taxi. The special emphasis is on poor visibility conditions. The regulation covering this is JAR-AWO (All Weather Operations). The JAR-AWO is made of i) Category I (CAT I) ii) Category II (CAT II)

iii) Category III (CAT III) iv) Low Visibility Take Off (LVTO)

v) Low Visibility Taxi (LV TAXI) The objective of CAT II / CAT III operations is to provide a level of safety when landing in low visibility conditions, equivalent to that of 'normal' operating conditions. Category II / Category III constitutes the main part of All Weather Operations (AWO). CAT I refers to good visibility i.e. 'normal' operating conditions. Decision Height (DH) To understand the concepts of CAT-II/CAT-III operations, it is essential to understand the term decision height (DH). Decision height is the wheel height above the runway elevation by which a go-around must be initiated unless adequate visual reference has been established and the aircraft position and approach path have been assessed as satisfactory to continue the approach and landing in safety. The DH is measured by means of radio-altimeter.

Runaway Visual Range (RVR): Another term encountered is the Runway Visual Range (RVR). It is the range over which a pilot of an aircraft on the centerline of the runway can see the runway surface markings or the lights delineating the runway or identifying its centerline.

Category II (CAT II) category II approach is a precision instrument approach and landing with decision height lower than 60m (200ft) but not less than 30m (100ft), and a runway visual range not less than 350m (1200ft). The main objective of CAT II operations is to provide a level of safety equivalent to other operations, but in more adverse weather conditions and lower visibility. CAT II weather minima allow sufficient visual references at DH to permit a manual landing (or a missed approach) to be executed. Category III (CAT III) The main difference between CAT II / CAT III operations is that Category II provides sufficient visual reference to permit a manual landing at DH, whereas Category III does not provide sufficient visual references and requires an automatic landing system. CAT Ill is divided in three sub-categories: CAT III A, CAT III B, and CAT III C, associated with three minima levels (CAT III A is associated with highest minima, and CAT III C with lowest minima). An automatic landing system is mandatory to perform Category III operations. Its reliability must be sufficient to control the aircraft to touchdown in CAT III A operations and through rollout to a safe taxi speed in CAT III B.

CAT IIIA A category III A approach is a precision instrument approach and landing with no decision height or a decision height lower than 100ft (30m) and a runway visual range not less than 700ft (200m).

CAT IIIB A category III B approach is a precision approach and landing with no decision height or a decision height lower than 50ft (15m) and a runway visual range less than 700ft (200m), but not less than 150ft (50m). CAT IIIC A category III C approach is a precision approach and landing with no decision height and no runway visual range limitation. CAT III C operations are not currently authorized by Airworthiness Authorities.
