The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by reports of multiple supplier notices of escapement (NOEs) indicating that seat track splice fittings were possibly manufactured with an incorrect titanium alloy material. This AD requires an inspection of seat track splice fittings to determine the material and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
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-SB530086-00 RB, Issue 001, dated October 18, 2024, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin B787-81205-SB530086-00 RB, Issue 001, dated October 18, 2024.

(2) Where table 1 of task 17 and task 18 of Boeing Alert Requirements Bulletin B787-81205-SB530086-00 RB, Issue 001, dated October 18, 2024, specifies collars having a part number (P/N) of “BACC30BS10S”, this AD requires replacing that text with “BACC30BS10S or BACC30BS10K”.
