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 a report of uncommanded movement of the Captain's seat in the forward direction that caused a rapid descent. This AD requires inspections of affected Captain's and First Officer's seats for missing or cracked rocker switch caps and for cracked or nonfunctional switch cover assemblies, a rocker switch cap pull test, marking of the seats, and applicable on-condition actions. This AD also limits the installation of affected seats. The FAA is issuing this AD to address the unsafe condition on these products.
For airplanes identified in paragraph (c)(1) of this AD: Within 30 days after the effective date of this AD, do a general visual inspection for cracked or missing rocker switch caps of the Captain's and First Officer's seats, in accordance with the Accomplishment Instructions of Ipeco Service Bulletin 380-25-06, Issue 03, dated July 17, 2024. For any switch that has a cracked or missing switch cap, replace the switch and bond the switch cap within 30 days after the effective date of this AD, in accordance with the Accomplishment Instructions of Ipeco Service Bulletin 380-25-06, Issue 03, dated July 17, 2024. Replacement may be delayed provided the airplane is operated under the provisions of Master Minimum Equipment List item 25-11-01-0, but no later than 120 days after the effective date of this AD.
For airplanes identified in paragraph (c)(1) of this AD: Within 30 days after the effective date of this AD, perform a general visual inspection for cracks of the switch cover assemblies and local areas and a functional test of the switch cover, in accordance with the Accomplishment Instructions of Ipeco Service Bulletin 380-25-06, Issue 03, dated July 17, 2024. Replace any cracked or nonfunctional parts within 30 days after the effective date of this AD, in accordance with the Accomplishment Instructions of Ipeco Service Bulletin 380-25-06, Issue 03, dated July 17, 2024.

For any rocker switch cap that is un-bonded or de-bonded (i.e., fails the test), bond the rocker switch cap, or replace the switch and bond the switch cap, within 30 days after the effective date of this AD, in accordance with the Accomplishment Instructions of Ipeco Service Bulletin 380-25-06, Issue 03, dated July 17, 2024.

(2) For any switch that has been replaced with a switch having a bonded cap as required by paragraph (g) of this AD, the actions required by paragraph (i) of this AD are not required.
