The FAA amends § 39.13 by adding the following new airworthiness directive: 2024-22-05 The Boeing Company: Amendment 39-22876; Docket No. FAA-2024-2008; Project Identifier AD-2024-00122-T. (a) Effective Date This airworthiness directive (AD) is effective December 31, 2024. (b) Affected ADs None.

(d) Subject Air Transport Association (ATA) of America Code 32, Landing gear. (e) Unsafe Condition This AD was prompted by a report that during manufacture of drag brace lower lock link assemblies for the main landing gear (MLG), a certain inspection was not performed.
