Airworthiness Directive · Amendment 39-22836 · Equipment/furnishings
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 determination that the flight deck door decompression panel can strike the captain's seat headrest if a flight deck or below the flight deck rapid decompression event occurs when the seat is in a certain position. This AD requires, for certain airplanes, replacing the affected captain's seat assembly. 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 certificate of airworthiness or original export certificate of airworthiness issued on or before the effective date of this AD, with a seat assembly having Boeing part number (P/N) S632Z301-21 (Ipeco P/N 3A380-0007-01-7) installed on the captain's side: Except as specified by paragraph (h) of this AD, at the applicable times specified in the “Compliance” paragraph of Boeing Special Attention Requirements Bulletin B787-81205-SB250294-00 RB, Issue 001, dated June 14, 2023, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Special Attention Requirements Bulletin B787-81205-SB250294-00 RB, Issue 001, dated June 14, 2023.
Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Special Attention Service Bulletin B787-81205-SB250294-00, Issue 001, dated June 14, 2023, which is referred to in Boeing Special Attention Requirements Bulletin B787-81205-SB250294-00 RB, Issue 001, dated June 14, 2023.
(1) Where the Boeing Recommended Compliance Time column of the table in the “Compliance” paragraph of Boeing Special Attention Requirements Bulletin B787-81205-SB250294-00 RB, Issue 001, dated June 14, 2023, refers to the Issue 001 date of Requirements Bulletin B787-81205-SB250294-00 RB, this AD requires using the effective date of this AD.
(2) Where Boeing Special Attention Requirements Bulletin B787-81205-SB250294-00 RB, Issue 001, dated June 14, 2023, specifies replacement with captain's seat assemblies having Boeing P/N S632Z301-31 (Ipeco P/N 3A380-0007-01-8), this AD requires installing that part number or a later-approved part number. Later-approved part numbers are only those that are approved as a replacement for the applicable captain's seat assembly and are approved as part of the type design by the FAA or The Boeing Company Organization Designation Authorization (ODA) after June 14, 2023 (the issuance date of Boeing Special Attention Requirements Bulletin B787-81205-SB250294-00 RB, Issue 001).
Replacement of the captain's seat assembly as required by paragraph (g) of this AD terminates the requirements of paragraph (h)(1) of AD 2016-19-04, for that captain's seat assembly only.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
