MAINTENANCE MANUAL
TIME LIMITS / MAINTENANCE CHECKS
1. Time Limits Maintenance Checks — General
A. Introduction
This chapter, in general, has been prepared in accordance with the Air Transport Association of
America (ATA 100 Specifications).
The maintenance program has been prepared by Gulfstream Aerospace Corporation to provide the
operator with information necessary to comply with the requirements of FAR 91, Sub Part E,
Section 91.409, Paragraph (f)(3) of the General Operating and Flight Rules of the Federal Aviation
Regulations.
This maintenance program is applicable to aircraft on a fleet wide basis regardless of the
regulations of the country in which the aircraft is registered. Aircraft of Non-United States registry,
consult the regulatory authority for the country of registry for requirements.
Airworthiness Limitations Requirements: Time Limited Components, 05-04-00, Airworthiness
Limitations, Baseline Life Limited Components, 05-04-01, Baseline Life Limited Components and
ASC 510 Airworthiness Limitations Instructions (ALI), 05-04-02, ASC 510 Airworthiness Limitations
Section must be met as stated.
All components not specifically listed are on condition and are monitored during scheduled system
operational tests.
Aircraft operating in a tropical zone, high humidity area, marine environment or an area of high
industrial pollution should be inspected more frequently.
It is the operator’s responsibility to obtain / establish the inspection requirements and time intervals
for equipment installed by the operator or the outfitting agency.
Inspection requirements for the engine, navigation, communication, certain avionics equipment and
APU will be determined by the appropriate manufacturer unless explicitly noted otherwise.
On any aircraft with more than 2000 landings, whenever any portion of the cockpit or cabin
structure, normally concealed behind equipment, furnishings or upholstery, is exposed by
modification or repair of the said equipment, furnishings or upholstery, then the exposed structure
should be given a thorough visual inspection for cracks, corrosion and loose fasteners. Effort should
be made, where possible by such measures as lifting the edges of trim panels, to see the structure
as far around the opened area as practicable. The extent of the inspection, defined by fuselage
stations and stringer numbers, plus aircraft flight hours and number of landings and the results of
the inspection shall be recorded in the aircraft logbook.
NOTE: This requirement may be waived if the area has been opened up and inspected within the
last 1000 landings.
Revisions to the original text are indicated by vertical lines in the left margin of the page, adjacent
to the revised material.
Active customer bulletins are part of Gulfstream’s recommended inspection program and are listed
in the Customer Bulletin Index. The Customer Bulletin Index can be found in the Maintenance
Library (MyGulfstream.com / Online Manuals).
NOTE: See Section Special Inspection Requirements, 05-06-00, Active Customer Bulletins Index
for information.
Unless otherwise noted, references to ASCs or CBs in chapter 5 apply to the initial release and
subsequent revisions of the identified ASC or CB.

MAINTENANCE MANUAL
It is the operator’s 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 are
accomplished by a trained and experienced NDT Inspector.
B. Terminology
Calendar Month – Indicates inspection may be accomplished any day of the month that it is due in.
NOTE: Unless otherwise specified, calendar month is applicable for monthly checks.
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. Condition
Monitoring is accomplished by appropriate means available to an operator for finding and solving
problem areas.
Functional Test – That procedure required to ascertain that a system or unit is functioning in all
aspects in accordance with minimum acceptable system or unit design specifications. These tests
may require supplemental ground support equipment and should be more specific and detailed than
an operational test.
Hard Time – This concept qualifies the type of component maintenance which imposes fixed limits
for component removal.
Hydrostatic Testing – That procedure which tests vessels containing fluids under pressure.
Inspection / Check – Visual inspection required to ascertain the serviceability of a part, assembly
system, specific interrelationship of parts that perform a functional operation, etc.
On Condition (OC) – This is a preventive primary maintenance process. It requires that an
appliance or part be periodically inspected or checked against some appropriate physical standard
to determine whether it can continue in service. The purpose of the standard is to remove the unit
from service before failing during normal operation.
Operational Test – That procedure required to ascertain only that a system or unit is operable.
Overhaul – Remove component from aircraft and disassemble to allow proper checking of
clearances, dimensions and for evidence of corrosion, distortion and contamination.
Scrap – End of useful life.
Service – Servicing operation including: cleaning, lubrication and condition of a component or
equipment.
Time in Service – With respect to maintenance time records, defined as the time from the moment
an aircraft leaves the surface of the earth until it touches it at the next point of landing.
NOTE: For the purposes of tracking maintenance requirements in the Gulfstream AMM, the terms
cycles and landings are equivalent.
C. Description of the Subsections
(1) Scheduled Maintenance Checks 05-01-00
This section contains all programmed maintenance operations and frequencies to be carried
out on the aircraft.
This section also includes Certification Maintenance Requirements (CMR) which are
mandatory fixed interval maintenance task requirements established during the aircraft
certification process.
Newly issued requirements and changes to existing requirements become effective as
defined by the new / changed information following publication date of the revision. Action is
05-00-00

MAINTENANCE MANUAL
to be accomplished at the earliest convenient time when maintenance is being accomplished
in the same area or no later than the next interval following the publication date of the revision
unless otherwise noted.
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, which start at date of manufacture. (Date of manufacture is the
date the aircraft rolls off the production line.)
• Upon outfitting completion, refer to Activation of Aircraft from Storage, 10-00-00,
Servicing.
The recommended maintenance operations to be performed on aircraft are listed in tabular
form as follows:
AMM Ref column This column list the location in the Maintenance Manual, by Chapter
and Section.
Description column This column list title of maintenance procedure to be performed.
CMP Ref Column This column list CMP (Computerized Maintenance Program) Code
to be consulted for procedure to be performed.
Initial / Repeat This column list the initial and repeat frequency for the requirement..
Column Any item in this column may be extended up to a factor of 15.
Examples: +15 hours, +15 days or +15 cycles unless noted “Not
subject to change by Gulfstream Operators. Exempt from overfly
provisions.”
NOTE
Accomplishment of tasks beyond the established interval, including
extensions, are not intended to be cumulative. The next due interval
shall be at the scheduled time or date as calculated from the due
time of the last completed inspection, not from the point of
inspection completion.
NOTE: The inspection frequencies for the wing NDT inspections are based on damage
tolerance analysis. These inspections cannot be accomplished any later than the
tolerances provided in Section 05-01-00.
(2) Manufacturer Time Between Overhaul/Scrap 05-02-00
This section lists all equipment not covered in Section 05-04-00 requiring a major overhaul /
