2024-23-11: 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: 2024-23-11 The Boeing Company: Amendment 39-22890; Docket No. FAA-2024-0463; Project Identifier AD-2023-00792-T. (a) Effective Date This airworthiness directive (AD) is effective January 6, 2025. (b) Affected ADs None. (c) Applicability This AD applies to The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes, certificated in any category, as identified in Boeing Alert Requirements Bulletin 737-27A1325 RB, dated July 14, 2023. (d) Subject Air Transport Association (ATA) of America Code 27, Flight controls. (e) Unsafe Condition This AD was prompted by a report of a non-conforming installation of spoiler wire bundles that led to unintended spoiler motion, including one instance of a flight spoiler hardover. Further investigation identified the potential for a time-limited hardover of more than one flight spoiler on the same wing, which can exceed full lateral control capability leading to loss of control of the airplane. The FAA is issuing this AD to address improper clearance between the spoiler control wire bundles and the adjacent structure, which can lead to damage to the wire bundle, causing unintentional spoiler motion. The unsafe condition, if not addressed, could result in loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Except as specified by paragraph (h) of this AD: At the applicable times specified in the "Compliance" paragraph of Boeing Alert Requirements Bulletin 737-27A1325 RB, dated July 14, 2023, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 737-27A1325 RB, dated July 14, 2023.
