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: a. Removing Airworthiness Directive (AD) 2020-05-12, Amendment 39-19860 (85 FR 14562, March 13, 2022); and b. Adding the following new AD: 2022-10-05 Gulfstream Aerospace Corporation: Amendment 39-22043; Docket No. FAA-2022-0511; Project Identifier AD-2022-00397-T. (a) Effective Date This airworthiness directive (AD) is effective May 9, 2022. (b) Affected ADs This AD replaces AD 2020-05-12, Amendment 39-19860 (85 FR 14562, March 13, 2020) (AD 2020-05-12). (c) Applicability This AD applies to all Gulfstream Aerospace Corporation Model GVII-G500 and GVII-G600 airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 27, Flight controls. (e) Unsafe Condition This AD was prompted by reports of two landing incidents in which the alpha limiter engaged in the landing flare in unstable air, resulting in high rate of descent landings and damage to the airplanes. The FAA is issuing this AD to address inappropriate alpha limiter engagement during the landing flare, which can limit pilot pitch authority during a critical phase of flight near the ground, and result in a high rate of descent landing with possible consequent loss of control of the airplane on landing. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Retained Requirements for Certain AFM Revisions for GVII-G500, With Revised Paragraph References This introductory text to paragraph (g) restates the requirements of the introductory text to paragraph (g) of AD 2020-05-12, with revised paragraph references.
