2023-20-10: 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: 2023-20-10 Bombardier, Inc.: Amendment 39-22569; Docket No. FAA-2023-1493; Project Identifier MCAI-2022-01105-T. (a) Effective Date This airworthiness directive (AD) is effective November 21, 2023. (b) Affected ADs None. (c) Applicability This AD applies to Bombardier, Inc., Model BD-700-2A12 airplanes, certificated in any category, serial numbers 70006 through 70129 inclusive. (d) Subject Air Transport Association (ATA) of America Code: 27, Flight controls. (e) Unsafe Condition This AD was prompted by a report that some of the multi-function spoiler (MFS) anti-rotation plates failed in-service due to a thin wall design. The FAA is issuing this AD to address MFS anti-rotation plate failures. The unsafe condition, if not addressed, could result in wear and failure of the inboard and outboard spoiler hinge pins, possibly resulting in a hinge no longer supporting the load, or unintended asymmetrical spoiler deployment, leading to reduced controllability of the airplane, or loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Replacement and Inspection (1) Within 36 months after the effective date of this AD, replace the left and right MFS No. 1, MFS No. 2, and MFS No. 3 anti-rotation plate part number (P/N) G05770140-103 and P/N G05770160-101 with P/N G05770140-105, including inspecting the MFS anti-rotation plates for any cracking and the hinge bolts for any evidence of rotation, in accordance with Part 2.B. of the Accomplishment Instructions of Bombardier Service Bulletin 700-27-7504, Revision 01, dated July 11, 2022. If any cracking or evidence of rotation is found, before further flight, repair using a method approved in accordance with the procedures specified in paragraph (i)(1) of this AD.
