2023-14-08: Flight Controls

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2023-14-08 Gulfstream Aerospace Corporation: Amendment 39-22508; Docket No. FAA-2023-0659; Project Identifier AD-2022-01404-T. (a) Effective Date This airworthiness directive (AD) is effective August 24, 2023. (b) Affected ADs None. (c) Applicability This AD applies to Gulfstream Aerospace Corporation Model GVII-G600 airplanes, certificated in any category, serial numbers 73001 through 73051 inclusive. (d) Subject Air Transport Association (ATA) of America Code 27, Flight Controls. (e) Unsafe Condition This AD was prompted by an addition of a life limit in the Airworthiness Limitations Section (ALS) for GVII-G600 inboard flap actuator yoke fittings. The FAA is issuing this AD to address decreased fatigue life of GVII-G600 inboard flap actuator yoke fittings and to prevent the GVII-G600 flap yoke from remaining in service beyond its life limit. The unsafe condition, if not addressed, could result in the flaps being jammed in position, if fracture occurred. Additional failures in the flap actuator force limiter, or flap yoke actuator disconnect, could result in asymmetric flap positions leading to a loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Incorporation of ALS Revisions Within 30 days after the effective date of this AD, revise the existing ALS of the Instructions for Continued Airworthiness (ICA) or inspection program for your airplane by establishing a life limit of 4,000 flight cycles for the left-hand part number (P/N) 73P5755033M005 and right-hand P/N 73P5755033M006 inboard flap yoke fittings. Note 1 to paragraph (g): The life limit in paragraph (g) of this AD is contained in table 2 in Section 05-10-10 of Gulfstream GVII-G600 Aircraft Maintenance Manual, Revision 9, dated November 15, 2022. (h) Alternative Methods of Compliance (AMOCs) (1) The Manager, East Certification Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the manager of the certification office, send it to the attention of the person identified in paragraph (i)(1) of this AD.
