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 Limits • Section 1.C. Structural Inspection Intervals / Procedures • Section 1.D. Certification Maintenance Requirements (CMR) (2) Airworthiness Limitations This section lists all components that have retirement (scrap / discard) times controlled by FAA-ACO. The retirement times (frequency) are not subject to change by Gulfstream operators. Aircraft without a record of the number of landings, a figure of one landing per 1.72 flying hours is considered acceptable. B. Safe-Life Limits The Safe Life Limits addresses those items that have been defined 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 T ables.

Certification Maintenance Requirements (CMR) (1) Introduction The following presents a list of all Gulfstream Certification 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 specified 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.
