Airworthiness Limitations Section A. Introduction The Airworthiness Limitations Section is Federal Aviation Administration approved and specifies maintenance required under Sections 43.16 and 91.403 of the Federal Aviation Regulations, unless an alternative program has been FAA approved. (1) Subsections - Details • Section 1.B. Safe Life Limited Items • Section 1.C. Principal Structural Element (PSE) Reporting Procedures • Section 1.D. Principal Structural Element (PSE) Inspections • Section 1.E. Certification Maintenance Requirements (CMR) (2) Airworthiness Limitations Each new model of Gulfstream aircraft, will have its own Airworthiness Limitations (AL). The AL speci fically addresses those items which have been identi fied through the certi fication process as being safe life (life limited) or damage tolerant and meet the de finition of a PSE. Aircraft without a record of the number of landings may calculate by using a ratio of one (1) landing per two (2) flying hours. (3) MRB Report MSG-3 structural inspection tasks which satisfy ALI requirements for accidental and environmental (corrosion) damage are listed in AMM Chapter 05-22-00 (Maintenance Review Board Report). The operator must consider both AMM Chapter 05-22-00 and Chapter 05-10-10 requirements when developing and maintaining a maintenance program. B. Safe-Life Limits The Safe Life Limits addresses those items that have been de fined as being life limited. The part number, quantity, item description and mandatory replacement times for these parts are included as shown in the following Life Limited Components Tables.

Principal Structural Elements Reporting Procedure Reporting of inspection results is required to ensure continued airworthiness of the fleet is maintained. This procedure contains the necessary reporting information which is to be used whenever a principal structural element inspection is accomplished. NOTE: Inspection results, both positive and negative, are to be reported to Gulfstream Maintainability Engineering. Complete Table 8 with inspection results. Return completed table to Gulfstream Maintainability Engineering, FAX 912-965-4704. Discrepancies must be reported within 24 hours. Discrepancies must be accompanied by digital photograph(s).

Principal Structural Element Inspection Requirements Table 10 contain a list of PSE along with the specific description, initial threshold, repeat interval and Computerized Maintenance Program (CMP) reference. NOTE: For PSE inspections with an MRB reference listed as inspection interval, see Scheduled Maintenance Checks, 05-20-00, Scheduled Maintenance Checks inspection table with same MRB reference to determine frequency. For inspections with a reduced recurring interval (i.e., 10,000 initial / 2,000 recurring) the next due inspection is dependent upon the initial inspection accomplishment. See Figure 1.

If time remaining after early compliance is greater than the recurring interval, the next inspection due is at the original initial due time. If time remaining after early compliance is less than the recurring interval, the next inspection due is at the recurring interval from the actual accomplished point.

MAINTENANCE MANUAL 05-10-10 Page 36 April 29/16 TEMPORARY REVISION 5-3 ### Page 37 E. Certi fication Maintenance Requirements (CMR) (1) Introduction The following presents a list of all Gulfstream Certi fication Maintenance Requirements (CMR), based on safety analyses, performed to meet requirements of FAR / JAR 25.1529, Instructions for Continued Airworthiness and other relevant requirements and engineering judgement. (2) Types The Certification Maintenance Requirements (CMR) are categorized into two types of CMR tasks as follows: (a) One star CMR (*) - The task and interval speci fied are mandatory and cannot be changed, escalated or deleted without the concurrence of the FAA -ACO. (b) Two star CMR (**) - The task intervals may be adjusted in accordance with an operator’s approved escalation practices or an approved reliability program, but the task may not be changed or deleted without prior FAA approval. (3) Maintenance Tasks NOTE: Unless otherwise specified, CMR tasks may be performed with a scheduling window as follows: •± 50 hours not to exceed the CMR interval + 50 hours between inspections •± 1 calendar month, not to exceed CMR interval +1 calendar month between inspections C checks or monthly inspections may be accomplished on any day of the calendar month that they are due. Flight hours and flight cycles are tracked from first flight. C Checks and calendar items (monthly checks) are clocked from Entry Into Service (EIS) after completion of initial out fitting installation.
