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: 2024-01-07 The Boeing Company: Amendment 39-22658; Docket No. FAA-2023-0429; Project Identifier AD-2022-00775-T. (a) Effective Date This airworthiness directive (AD) is effective March 7, 2024. (b) Affected ADs None. (c) Applicability This AD applies to all The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series 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 an evaluation by the design approval holder that the force limiter assemblies for the lateral control mechanism are not breaking out within the maximum design force requirements. The FAA is issuing this AD to address the force limiter assemblies not breaking out within the maximum design force requirements. The unsafe condition, combined with a lateral control system jam or restriction, could result in the loss of lateral control from the wheel and potentially affect continued safe flight and landing. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions For airplanes identified in paragraphs (g)(1) and (2) of this AD: Except as specified by paragraph (h) of this AD, at the applicable times specified in the "Compliance" paragraph of Boeing Alert Requirements Bulletin 777-27A0124 RB, dated October 27, 2021, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 777-27A0124 RB, dated October 27, 2021.
