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 Inspection Requirements • 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. NOTE: Mandatory life limitations and inspections applicable to aircraft having ASC 99 , European Aviation Safety Agency (EASA) certi fication. Where these limitations or inspection requirements are different from those limitations approved by the Federal Aviation Administration (FAA), the EASA approved data applies. Where no supplemental EASA information is provided, the FAA approved data is applicable. (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 FAA and EASA 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 9 with inspection results. Return completed table to Gulfstream Maintainability Engineering (for contact information see Description of the Subsections, 05-00-00, Time Limits / Maintenance Checks ). Discrepancies must be reported within 24 hours. Discrepancies must be accompanied by digital photograph(s). Table 9: PSE Inspection Results PSE Number A/C Serial Number A/C Tail Number Part Number(s) [if applicable] A/C Hours A/C Landings Date of Inspection Discrepancies Found Yes (If yes information below must be completed.) No Location FS BL WL Size Orientation D. Principal Structural Element Inspection Requirements Table 11 contains a list of PSE along with the speci fic description, initial threshold, repeat interval and Computerized Maintenance Program (CMP) Reference. All PSE inspections (with the exception of those that are satisfied by an MRB task) must be tracked by the appropriate time measurement. Airframe PSE items will reflect the total flight/hours and flight cycles of the aircraft. Line Replaceable Unit (LRU) PSE items will be tracked by the total times (Time Since New / Cycles Since New, TSN/CSN) of the component. NOTE: For PSE inspections with an MRB reference listed as inspection interval, see Scheduled Maintenance, 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.

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: CMR tasks may be performed with a scheduling window of +/- 50 hours not to exceed the CMR interval + 50 hours between inspections, unless otherwise specified.
