Airworthiness Directive · Amendment 39-22876 · Landing gear
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. 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 required inspection was not performed. This AD requires doing a check of maintenance records or an inspection to determine if certain drag brace lower lock link assemblies are installed, and applicable on-condition actions. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
For airplanes with an original airworthiness certificate or original export certificate of airworthiness issued on or before the effective date 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 B787-81205-SB320048-00 RB, Issue 001, dated November 20, 2023, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin B787-81205-SB320048-00 RB, Issue 001, dated November 20, 2023. The actions specified in Boeing Alert Requirements Bulletin B787-81205-SB320048-00 RB, Issue 001, dated November 20, 2023, apply to airplanes not listed in Boeing Alert Requirements Bulletin B787-81205-SB320048-00 RB, Issue 001, dated November 20, 2023.
