MAINTENANCE REGULATIONS CASR PART 66page 1

IntroductionFrom 27 June 2011, Part 66 introduces a new system for licensing aircraft maintenance engineers (LAMEs). The new continuing airworthiness suite also includes:

» CASR Part 147, which covers maintenance training organisations (MTO)

» CASR Part 42, which covers continuing airworthiness for aircraft and aeronautical products

» CASR Part 145, which covers approved maintenance organisations.

Part 66 licensing regulations replace regulation 31 of the Civil Aviation Regulations 1988 (CAR 31) and use the A, B1, B2 and C categories and type ratings used by the European Aviation Safety Agency (EASA).

This booklet gives you basic information about CASR Part 66 licensing, the privileges of the new licence and a comparison with the CAR 31 licence, as well as training requirements. This is only an introduction to Part 66 and does not replace the regulations or related documents.

You will find CASR Part 66 and its related manual of standards (MOS) and acceptable means of compliance/guidance material documents on the CASA website at www.casa.gov.au

Overview of the new systemThe new continuing airworthiness system changes the arrangements for aircraft maintenance. While the new requirements for licensing AMEs come in on 27 June 2011, the Part 42 & 145 requirements only apply to regular public transport aircraft and will be implemented progressively over the two year transition period which starts on 27 June 2011.

For licensed AMEs (LAMEs), the new system has an immediate impact. Any person applying for a new licence or rating after 27 June 2011 will do so under Part 66. But there are provisions to accept the CAR 31 exam and SOE standards for four years.

The Part 42 and 145 requirements will only apply to LAMEs if they are working on RPT aircraft and their aircraft maintenance organisation (AMO) has become a Part 145 organisation.

The role of the LAME under the new regulationsSection 20AB of the Civil Aviation Act 1988 means anyone carrying out maintenance on Australian aircraft or aeronautical products must have an appropriate authorisation.

From 27 June 2011, that authorisation will be a CASR Part 66 licence which replaces the CAR 31 licence. CAR 30 organisations performing maintenance on RPT aircraft will transition from 27 June 2011 and become Part 145 organisations. For all other aircraft, the CAR 30 system will still apply.

During transition, Part 66 licence holders will continue to work for maintenance organisations holding CAR 30 authorisations, or work independently. If the organisation you work for becomes a Part 145 AMO, the new Part 42 and 145 regulations will apply to you.

An amendment to Part 4A, Division 5 of the CAR (Who may carry out maintenance) recognises Part 66 licences rather than CAR 31 licences.

How certifications for maintenance completion are made, and the way maintenance releases are used under the CAR, will remain the same during the transition period. The only difference is the person coordinating the maintenance, certifying for the completion of maintenance and issuing aircraft maintenance releases will be the holder of a Part 66 licence rather than a CAR 31 licence.

Implications of Part 42 and Part 145 for licence holdersCASR Part 42 covers the continuing airworthiness requirements for aircraft and aeronautical products. The permission to use a Part 66 licence is in Subpart 42D of Part 42. This permission comes into effect once the Part 66 licence holder is employed in a Part 145 AMO. If you’re a licence holder employed by a Part 145 organisation you will have two years to gain human factors training, which will be provided by the Part 145 AMO, or a Part 147 maintenance training organisation (MTO) approved to do so.

The certification process for completion of maintenance on an aircraft or an aeronautical product is fundamental to airworthiness control. It verifies that all maintenance has been carried out to required standards by properly qualified individuals, and underpins the mechanism by which aircraft or products are returned to service, and ongoing maintenance requirements are determined. As aircraft become more complex, the integrity and robustness of the certification process is even more critical to aviation safety.


In Part 42 there are two levels of certifying the completion of maintenance on aircraft or aeronautical products.

1. Maintenance certification. Licence holders certify for maintenance work done on aircraft systems covered by their licence. Category C licence holders cannot provide maintenance certifications. The licence holder issuing the certificate of release to service (CRS) relies on the individual maintenance certifications to confirm that all maintenance has been carried out in accordance with approved maintenance data and procedures.

2. Certificate of release to service (CRS) for the aircraft. The CRS must be issued before an aircraft or an aeronautical product can be returned to service after maintenance. A CRS can be issued by the holder of a category A, B1 or B2 licence, except following base maintenance on large aircraft in a Part 145 AMO. Category C licence holders with the appropriate type rating can issue a CRS in a Part 145 AMO for a large aircraft following base maintenance.

Certification of release to service following line maintenance An appropriately licensed and authorised category A, category B1 or category B2 licence holder may issue a CRS.

Certification of release to service following base maintenance For base maintenance of large aircraft in a Part 145 AMO, the CRS is issued by an appropriately licensed and authorised category C licence holder.

The category C licence holder is supported by a team of authorised category B1 and B2 licence holders. They carry out or supervise the performance of specific base maintenance tasks. The tasks must be carried out in accordance with the approved maintenance data and procedures. When they are satisfied the tasks have been carried out properly, they issue the maintenance certification for those tasks.

The certifying category C licence holder issues the CRS when satisfied the complete maintenance process has been carried out in accordance with the approved maintenance data and procedures.

Critical Control System MaintenancePart 42 refers to critical control system maintenance. This is maintenance that if not carried out correctly, may result in a failure, malfunction, or defect that would endanger the safe operation of the aircraft. It does not include optional dual flight control maintenance.

When a LAME carries out critical control system maintenance, an independent individual must inspect the part of the aircraft control system on which the maintenance was carried out and make an appropriate record for the maintenance before a CRS can be issued.

An independent individual cannot be the same person who carried out the maintenance; and did not perform maintenance certification for the maintenance. They must be a certifying employee of the AMO and authorised to perform maintenance certification for the maintenance, or for similar maintenance carried out on another aircraft with an aircraft control system of similar technology and construction.

Certification authorisations under Part 145The basic Part 66 licence confirms that at the time the category or subcategory licence and aircraft type rating was issued, the holder met the knowledge and experience standards.

Certification authorisations are issued by Part 145 AMOs and are only valid while the licence holder works for that AMO. To obtain a certification authorisation, the licence holder must satisfactorily complete all training required by the AMO’s approved procedures and, if necessary, the procedures of the customer’s airline.

Only those holding a valid Part 66 licence with an appropriate certification authorisation may perform maintenance certifications and issue a CRS. They are said to be appropriately licensed by CASA and authorised by the AMO. The authorisation becomes invalid if their Part 66 licence becomes invalid.


The new Part 66 licence structure Part 66 provides for licences to be issued with any of the following categories and subcategories:

Category A

» A1 – turbine-engined aeroplanes

» A2 – piston-engined aeroplanes

» A3 – turbine-engined helicopters

» A4 – piston-engined helicopters

Category B1

» B1.1 – turbine-engined aeroplanes

» B1.2 – piston-engined aeroplanes

» B1.3 – turbine-engined helicopters

» B1.4 – piston-engined helicopters

Category B2

» B2 - aircraft (aeroplanes and helicopters)

Category C

» Large aircraft in a base maintenance activity

Part 66 licence privilegesThe table on page 8-9 compares CAR 31 licence privileges to the new CASR Part 66 privileges.

In June 2011, when CAR 31 licences are converted to Part 66 licences, CASA will apply ‘exclusions’ to the Part 66 licence so that the privileges of the old and new licences match. The table on pages 10-12 lists those exclusions.

Details of licence privileges, aircraft systems, designations, conditions and limitations, and other related information, can be found in the Part 66 manual of standards (MOS) and the associated acceptable means of compliance/guidance material documents.

Privileges of category A licenceThe category A licence only applies to work being performed in a Part 145 AMO.

Category A licences are issued with one or more of the subcategories A1, A2, A3, A4. The holder of a subcategory A1, A2, A3 or A4 licence who has been type- and task-trained, and then authorised by the Part 145 AMO for the aircraft, may perform maintenance certification for the maintenance activity and issue a CRS for the aircraft following completion of specific and limited maintenance activities mentioned in the Part 145 MOS. Category A licences are not endorsed with specific aircraft type ratings by CASA.

Category A licence holders may not supervise the work of others for maintenance certification purposes. A second person could be present during the maintenance task and be assisting the category A licence holder. However, the assistant would be unable to provide any maintenance actions - tasks needing to be observed or supervised to ensure they were carried out correctly.

Category A licence holders may only issue a CRS when maintenance certifications have been performed only by a category A licence holder. If a category B1 or B2 licence holder

has issued the maintenance certifications for maintenance they have carried out on the aircraft then the category A licence holder is not permitted to issue the CRS.

Privileges of category B1 licenceCategory B1 licences are issued with one or more of the subcategories B1.1, B1.2, B1.3, B1.4. If you hold a subcategory B1.1, B1.2, B1.3, or B1.4 licence, you may perform maintenance certification for maintenance work within the scope of the licence, and may also issue a CRS for the aircraft (not in base maintenance of large aircraft in a Part 145 AMO) following completion of all maintenance certifications.

Each of the B1 subcategories covers aircraft structure, powerplant, mechanical and electrical systems. These include replacement of avionic line replaceable units (LRUs) where operational checks, built-in test equipment, or the aircraft’s maintenance system can demonstrate they are functioning correctly.

If the maintenance is for a type-rated aircraft, you must hold the appropriate aircraft type rating. The licence holder may supervise others for maintenance certification.

These licence holders may also undertake any work covered by a subcategory A1, A2, A3 or A4 included on the licence.

Privileges of category B2 licence If you hold a category B2 licence, you may perform maintenance certification within the scope of the licence and issue a CRS for an aircraft (not in base maintenance of large aircraft in a Part 145 AMO) following completion of all maintenance certifications. The scope of the B2 licence includes avionic, electrical systems and the instrument and electrical subsystems of mechanical, powerplant and structural systems. The licence holder may supervise others for maintenance certification purposes and requires a rating for type-rated aircraft.

The category B2 licence does not automatically include category A licence privileges. However, if you hold a category B2 licence you can apply for, and gain, a category A licence if you meet category A licence training and experience requirements.

Privileges of category C licence Category C licences are for large (type-rated) aircraft for base maintenance purposes in a Part 145 AMO, permitting the holder to issue a CRS for large aircraft following base maintenance.


Type-rated aircraft The Part 66 advisory material lists aircraft requiring you to have a type rating. These type-rated aircraft include large aircraft – aeroplanes over 5,700kg MTOW, multi-engine helicopters, and aircraft (including, where appropriate, a particular engine type) CASA has designated.

CASA designates type ratings for small aircraft, or for specific engines, if CASA considers that type training would improve safety, taking into account issues such as complexity, new technology and Australian Transport Safety Bureau recommendations.

Aeroplanes below 5,700kg can be covered by category B1 and category B2 licences, but within the scope of the licence, and normally without further rating requirements.

The definition of aircraft type in CASR Part 66 is:

(a) a particular type, or type and model, of large aircraft with a particular type of aircraft engine; for example, Airbus A310 (GE CF6), Boeing 747-400 (RR RB211), or

(b) a large aircraft with a particular type of aircraft engine; for example, non-rated aircraft (PWC PT6), non-rated aircraft (Honeywell TPE331), or

(c) a small aircraft with a particular type of aircraft engine; for example, small aircraft (PWC PT6), small aircraft (Honeywell TPE331).

Permission for the B1 licence holder to perform maintenance certifications and issue CRS for the powerplant of aircraft types (b) and (c) above is gained by holding those aircraft type ratings.

A category B1 licence holder would be permitted to work on the mechanical, electrical and structural systems of those aircraft via the holding of the appropriate licence; for example, subcategory B1.1. Holding ratings for aircraft types (b) and (c) is not relevant to B2 and C licence holders.

Summary of the rules for converting a CAR 31 licence to a Part 66 licence

1. A LAME obtaining a B1 licence at conversion will automatically gain an A1 subcategory licence.

2. A CAR 31 licence with one or more group 20 type ratings for the electrical, instrument and radio categories will convert to a category B2 licence with the same type rating(s).

3. A CAR 31 licence with the electrical and either airframe or engine categories (not including instrument or radio categories), will convert to a category B1 licence, as the electrical aspect is common to the category B1 and B2 licences.

4. A CAR 31 licence with group 20/21 airframe and engine categories will convert to a subcategory B1.1 licence excluding systems designated as being electrical or avionic; and electrical/instrument aspects of systems designated as being mechanical, powerplant or structural; for example, the electrical and instrument aspects of a mechanical system such as landing gear. This is covered by a CAR 31 licence with electrical and instrument categories. Under Part 66, the instruments and electrical aspects of a landing gear system are covered by both the category B1 and B2 licences.

5. The CAR 31 lower group ratings are converted with the cross-category privileges as specified in the CAO 100.90-95 series.

6. At the time of conversion, differences between a CAR 31 licence and a Part 66 licence are managed by using exclusions and additional privileges. Exclusions limit the privileges of the Part 66 licence to match the privileges of the CAR 31 licence. See table on pages 10-13 for the full list of exclusions.

7. You can have an exclusion removed by providing CASA with evidence that you have met the relevant competencies. This evidence could come from an LMA, line extension or an equivalent authorisation such as an overseas licence.

EXCLUSION LISTING - Updated as of 2 June 2011

An exclusion or limitation [number – column 1 : description – column 2], is applied to the Category B1 or B2 licence and/or a type rating listed in column 3, unless the licence holder has the particular CAR 31 category/group and rating listed in column 4. An additional privilege is applied to a Part 66 licence where the category B1 or B2 licence does not include a CAR 31 cross-category privilege.

For example, ‘Compensation of direct reading magnetic compasses’ is included in the privileges of a CAR 31 airframe category licence with instrument cross-category privileges. A CAR 31 airframe category licence converts into a Part 66 category B1 licence. The B1 licence does not include the compass compensation privilege. Therefore, that privilege is added to the B1 licence in the form of ‘I-1’ (Part 66 Manual of Standards, Table 1 explains when this privilege applies).

Additional privileges

Note 1: the exclusion would be still applied to the licence if the LAME holds the listed group but the CAR 31 licence has a relevant limitation for that system/subsystem endorsed on the licence.

Part 66 training standards and Part 147 organisationsCASA has integrated its licensing requirements with the nationally endorsed competency-based training package under the Australian Quality Training Framework (AQTF) arrangements. This competency-based system replaces the current CASA-administered theory examinations and practical schedule of experience (SOE) requirements.

For Part 66 licensing, CASA will only recognise training outcomes from CASA approved and oversighted CASR Part 147 maintenance training organisations (MTOs). The MTO will provide training and assessments for category, subcategory and aircraft type rating training.

You will find a full explanation of the basic knowledge and competency requirements at www.casa.gov.au, under the maintenance personnel licensing section. The additional licence category experience required is detailed below.

Licence category experience requirementsAn applicant for an aircraft maintenance engineer’s licence must have the following practical experience:

1. Category A and subcategory B1.2 and B1.4 licences — practical maintenance experience in carrying out maintenance on operating aircraft and in training as follows.

Licence category Amount of practical experience

A licence 2 yearsB1.2 or B1.4 licence 3 years

2. Category B2 and subcategory B1.1 and B1.3 licences — practical maintenance experience in carrying out maintenance on operating aircraft as follows.

Licence category Amount of practical experience

B1.1 or B1.3 licence or B2 licence

4 years

3. Category C licence:

» Three years of experience exercising category B1.1, B1.3 or B2 privileges on large aircraft including at least one year of experience of base maintenance or

» Five years of experience exercising category B1.2 or B1.4 privileges on large aircraft including at least one year of experience of base maintenance or

» for an applicant holding an academic degree in a technical discipline from a university or other higher educational institution recognised by CASA, three years of carrying out maintenance on operating aircraft, including at least six months of observation of base maintenance tasks.


3. Can I hold a category or sub-category of licence without a specific aircraft type rating?

Yes, providing you are fully trained and eligible for the category or sub-category of licence, CASA will issue you that licence with or without a specific aircraft type rating.

If you do not have the rating for an aircraft listed in the Part 66 advisory material then you cannot issue a CRS for that aircraft. However, you may still exercise the privileges of the licence on those aircraft that do not require ratings and are covered by the category or sub-category of your licence.

4. How do I gain a specific aircraft type rating on my licence?

To gain a specific type rating, you must hold an appropriate B1/B2 category or subcategory of licence. If your category or subcategory licence has an exclusion, then the aircraft type rating would carry the same exclusion. You would then need to:

(1) Attend, and pass, an approved course relevant to the B1 or B2 category/subcategory you are seeking a rating for (approved type courses will include both theory and practical); or

(2) If you have an overseas licence and rating, apply to CASA for recognition of the type rating.

frequently asked questions

1. Will I be able to use a B1 and B2 category licence in general aviation?

Yes, unless the aircraft is large or complex. Category B1 and B2 licence holders can perform maintenance certification and issue a CRS for general aviation (small or simple) aircraft.

2. I work for an airline that does not have propeller driven aeroplanes. Do I need to do the propeller training to get my licence?

If you are applying for a subcategory B1.1 or B1.2 licence, you do not need to do propeller theory and practical, unless you want to work on propeller-driven aeroplanes. You would gain a B1.1 or B1.2 licence with a propeller exclusion. If you subsequently want to work on propeller-driven aeroplanes, you would need to complete all propeller training, to have the exclusion removed.

B2 licence applicants will need to undertake adequate training to allow them to maintain and certify for propeller control systems.

5. If I hold a category B2 licence, can I certify for light aircraft without further type training?

Yes, unless the aircraft is large or complex (ie type rated). Holding a category B2 licence without a type rating allows you to perform maintenance certification and issue a CRS for work done on the aircraft, in accordance with any exclusions on the licence.

A person holding a category B2 licence without exclusions, has equivalent privileges to a person with electrical, instrument and radio group rating privileges under CAR 31, so would be able to perform maintenance certification and issue a CRS for electrical, instrument and radio maintenance.

6. If I qualify for a category B2 licence, will I also qualify for a category A licence?

No, you need additional competencies for a category A licence.

The categories you obtain depend on the competency assessment; either at the time of conversion, or by the Part 147 MTO. If you achieve all category A competencies, you would be entitled to the category A licence. If the conversion exercise determined you have not yet achieved them, you would not get the category A licence because of the missing competencies.

7. If I qualify for a category B1 licence, will I also qualify for a category A licence?

Yes. If you are eligible for a category B1 licence at the time of conversion, you are also be eligible for a category A licence.

8. How long do I have after 27 June 2011 to qualify for a Part 66 licence using the CAR 31 system, that is the basic exams and the SOE?

CASA will continue to provide CAR 31 basic examinations and assessment of SOE for four years, until 26 June 2015.

Type-rating course theory credits will also continue to be valid for licensing for four years, until 26 June 2015.


9. Who sets the requirements for category A, B1 and B2 licences for transitional training?

The Government publishes the Aeroskills Training Package. The Aeroskills Training Package delivers the CASA knowledge syllabus. If by transitional training you mean the training required to remove exclusions, then you would need to gain the competencies of the package to have the exclusions removed.

10. Will aircraft such as Metros and Beech 1900s become type rated, where currently they are not?

Yes, all large aircraft would become type rated. However, CASA may choose not to list aircraft considered large but simple. Large aircraft means:

» an aeroplane with a maximum take-off weight of more than 5 700kg MTOW or

» a twin-engined helicopter.

Personnel who use lower CAR 31 group ratings to maintain such aircraft can expect to be issued with the aircraft type ratings by the CASA licence conversion process.

11. I will be working for a maintenance organisation that hasn’t transitioned to Part 145 or Part 42. Do I need to be authorised by the organisation to exercise my licence privileges?

From 27 June 2011, a LAME with a Part 66 licence will continue to exercise licence privileges in the same way. Once the organisation becomes a Part 145 AMO, the new rules will apply and the LAME will need to be authorised by the AMO to perform their licence privileges.
