TIME LIMITS / MAINTENANCE CHECKS1. Introduction

A. GeneralThis chapter, in general, has been prepared in accordance with the Air Transport Association ofAmerica (ATA) 100 Specifications.The maintenance program has been prepared by Gulfstream Aerospace Corporation to provideoperator with information necessary to comply with requirements of FAR 91, Sub Part E, Section91.409, Paragraph (f)(3) of the General Operating and Flight Rules of the Federal AviationRegulations.This maintenance program is applicable to aircraft on a fleet wide basis regardless of the regulationsof the country in which aircraft is registered. Aircraft of Non-United States registry, consult theregulatory authority for country of registry for requirements.Time Limited Components, 05-04-00, Time Limited Components and Special Inspections, 05-05-00,Inspection / Check requirements must be met as stated.All components not specifically listed are on condition and are monitored during scheduled systemoperational tests.Aircraft operating in a tropical zone, high humidity area, marine environment or an area of highindustrial pollution should be inspected more frequently.It is the operators responsibility to obtain / establish inspection requirements and time intervals forequipment installed by operator or outfitting agency.It is the operators responsibility to ensure all steps required to comply with nondestructive testing(NDT) (i.e. Radiographic, Ultrasonic, Eddy current, Tap Test, etc.) of a NDT procedure areaccomplished by a trained and experienced NDT Inspector.Inspection requirements for engine, navigation, communication, certain avionics equipment and APUwill be determined by the appropriate manufacturer unless explicitly noted otherwise.On any aircraft with more than 2000 landings, whenever any portion of cockpit or cabin structure(normally concealed behind equipment, furnishings or upholstery) is exposed by modification orrepair of said equipment, furnishings or upholstery, then exposed structure should be given athorough visual inspection for cracks, corrosion and loose fasteners. Effort should be made wherepossible (by such measures as lifting edges of trim panels), to see structure as far around openedarea as practicable. The extent of inspection (defined by fuselage stations and stringer numbers) plusaircraft flight hours and number of landings and results of inspection shall be recorded in aircraftlogbook.NOTE: This requirement may be waived if area has been opened up and inspected within the last

1000 landings.Revisions to the original text are indicated by vertical lines in left margin of page, adjacent to revisedmaterial.

Active customer bulletins are part of Gulfstreams recommended inspection program and are listed inGeneral, 05-06-00, Active Customer Bulletins Index of this chapter. Any customer bulletins releasedafter publication of this index are active and will be added to this index in next revision.

B. TerminologyTime In Service With respect to maintenance records, means the time from the moment an aircraftleaves the surface of the earth until it touches it at the next point of landing.

Overhaul Remove component from aircraft and disassemble to allow proper checking ofclearances, dimensions and for evidence of corrosion, distortion and contamination.Operational Test That procedure required to ascertain only that a system or unit is operable.Functional Test That procedure required to ascertain that a system or unit is functioning in allaspects in accordance with minimum acceptable system or unit design specifications. These testsmay require supplemental ground support equipment and should be more specific and detailed thanan operational test.Hard Time (HT) This concept qualifies the type of component maintenance which imposes fixedlimits for component removal.On Condition (OC) This is a preventive primary maintenance process. It requires that an applianceor part be periodically inspected or checked against some appropriate physical standard to determinewhether it can continue in service. The purpose of the standard is to remove the unit from servicebefore failing during normal operation.Condition Monitoring (CM) This is a maintenance process for items that have neither Hard Time (HT) nor On Condition (OC) maintenance as their primary maintenance process. ConditionMonitoring is accomplished by appropriate means available to an operator for finding and solvingproblem areas.Scrap End of useful life.Inspection / Check Visual inspection required to ascertain serviceability of a part, assemblysystem, specific interrelationship of parts that perform a functional operation, etc.Service Servicing operation including cleaning, lubrication and condition of a component orequipment.Hydrostatic Testing That procedure which tests vessels containing fluids under pressure.Calendar Month Indicates inspection may be accomplished any day of the month that it is due in.NOTE: For the purposes of tracking maintenance requirements in the Gulfstream Aircraft

Maintainence Manual (AMM), the terms cycles and landings are equivalent.C. Section Breakdown

SECTION 05-01-00 SCHEDULED MAINTENANCE CHECKSThis section contains all programmed maintenance operations and frequencies to be carried out onaircraft.Newly issued requirements and changes to existing requirements become effective as defined by thenew / changed information following its receipt. Action is to be accomplished at the earliestconvenient time when maintenance is being accomplished in the same area or no later than the nextinterval following publication date or receipt of revision.New aircraft in outfitting centers may use the following guidelines for inspection requirements:

Flight hours and landings will remain accumulative from initial logbook entries. Calendar time compliance may be adjusted to begin on the date out of outfitting. Exceptions are

Wing Tank Interior - Inspection, 72 month structural inspection and corrosion inspections whichstart at date of manufacture. Date of manufacture is date aircraft rolls off production line.

Upon outfitting completion, see Activation of Aircraft from Storage, 10-00-00, Servicing.The recommended maintenance operations to be performed on aircraft are listed in tabular form asfollows:

E. Hydrostatic Testing of Bottles Charts and NotesNOTE: Hydrostatic test and service life requirements of the following bottles are defined by FAA

Order 8300.10 02-01A Handbook Bulletin for Airworthiness (HBAW) dated 04 September2002. All cylinders / spheres used as aircraft equipment must be maintained as follows:

DOT specification cylinders including spheres must be inspected and tested asrequired by Title 49 CFR, Part 180, Section 180.205

Cylinders including spheres manufactured under an exemption issued by RSPA mustbe inspected and tested as required by the terms of the exemption.

All other cylinders including spheres must be inspected and tested as required by Title49 CFR, Part 180, Section 180.205 as it applies to DOT 3HT cylinders, unlessalternative testing and inspection procedures are specified by the manufacturer orreferenced authority.

Operators with heavy maintenance checks that are accomplished in phases orsegments are required to have a procedure in place to check cylinders during thatphase or segment of their heavy maintenance checks in which maintenance of highpressure cylinders would normally occur.

See FAA Order 8300.10 02-01A (HBAW) for additional information.
