TIME LIMITS / MAINTENANCE CHECKS
1. Time Limits / Maintenance Checks — General
A. Introduction
This maintenance program has been prepared by Gulfstream Aerospace Corporation to provide
operators with all information necessary to comply with Federal Aviation Administration (FAA)
requirements of Part 91, Subpart E, Section 91.409, paragraph (f)(3), Part 125, Subpart G, Section
125.247, paragraph (e)(2) and Part 135, Subpart J, Section 135.421, paragraph (a) of the Federal
Aviation Regulations. Additionally, the information contained herein will enable operators to comply
with the requirements of Part 91, Subpart E, Section 91.409, paragraph (f)(4) and Part 135, Subpart
J, Section 135.411, paragraph (a)(2) to construct a suitable maintenance program.
Gulfstream has prepared the Gulftream GVI (G650) maintenance program with the intent of
providing the maximum amount of flexibility for the aircraft operator. The Aircraft Maintenance
Manual (AMM) Chapter 5 contains all requirements of the MSG-3 derived Maintenance Review
Board (MRB) Report, in addition to Gulfstream recommended inspections.
Active customer bulletins are part of Gulfstream’s recommended inspection program and are listed
in the Customer Bulletin Index.
NOTE: For customer bulletin description see Section 05-30-00 Special Inspection Requirements.
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.
A complete glossary of terms and definitions applicable to the Gulftream GVI (G650) Scheduled
Maintenance Program can be found in the Maintenance Review Board Report section of this
chapter.
Lubrication requirements specified in this section do not represent the total lubrication provisions for
the aircraft. See Chapter 12 - Servicing and appropriate manufacturer maintenance publications for
additional lubrication recommendations.
Aircraft based, or frequently operating, in a tropical zone, high humidity area, marine environment or
area of high industrial pollution should be inspected more frequently.
In order to maintain a sterile potable water system, intervals for water system sterilization should be
established by each operator based upon their operating environment, water servicing resources
and in-service experience.
B. Engine Programs
The Rolls-Royce BR700-725A1-12 MRB Report engine program is an on-wing program only.
On-wing engine maintenance tasks and instructions are provided in the Aircraft Maintenance
Manual. In addition, operators must consult the Rolls-Royce Time Limits Manual (TLM), Publication
Ref. T-725-7BR Airworthiness Limitations Section (ALS) to maintain the continued airworthiness of
the engine.
An operator may use either the “Task Oriented” maintenance program listed in this chapter or a
manufacturer’s “Hard Time” program under the following engine manufacturer recommendations:
NOTE: “Task Oriented” is sometimes referred to as “On Condition”. “Hard Time” is sometimes
referred to as “Fixed Interval”.
• Operators using the Task Oriented Maintenance Program contained in AMM Chapter 5 and
the MRB Report may refer to Rolls Royce Generic EMP document, BR725 Engine for G650
- “Engine Management Programme ‘Task Oriented’ Operated Engines” for the Rolls-Royce
minimum recommended work package.

MAINTENANCE MANUAL
• Operators using the manufacturer’s Hard Time Program may refer to Rolls Royce Generic
EMP document, BR725 Engine for G650 - “Engine Management Programme ‘Hard Time’
Operated Engines” for the Rolls-Royce minimum recommended work package.
• Operators who choose to transition from one maintenance program to the other, should
consult the appropriate Rolls-Royce EMP document for guidance.
At first “A” Check after entry into service, the operator is required to declare which engine
maintenance program they intend to follow with their local regulatory authority.
C. Time In Service
With respect to maintenance time records, time in service means the time from which an aircraft
leaves the surface of the earth until it touches again at the next point of landing.
NOTE: For the purposes of tracking maintenance requirements, the terms cycles and landings are
equivalent.

F. Manufacturer Recommended Inspection Program Tasks
Manufacturer Recommended Inspection Program (MRIP) tasks are derived external to the MSG-3
process and reflect Gulfstream’s recommendations for enhanced reliability and economic benefit.
MRIP tasks may be in addition to or have a more frequent interval than an MRB task.
Table 1 lists the MRIP tasks contained within AMM Chapter 5 as well as their history. Refer to the
applicable Chapter 5 section for task intervals.
