[Docket No. FAA-2024-2136; Project Identifier AD-2023-00296-T] RIN 2120-AA64

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 2019-14-13, which applies to all The Boeing Company Model 767-200, - 300, -300F, and -400ER series airplanes. AD 2019-14-13 was prompted by reports of uncommanded fore and aft movement of the Captain's and First Officer's seats. AD 2019-14-13 requires identifying the part number, and the serial number if applicable, of the Captain's and First Officer's seats, and applicable on-condition actions for affected seats. AD 2019-14-13 also requires a one-time detailed inspection and repetitive checks of the horizontal movement system (HMS) of the Captain's and First Officer's seats, and applicable on-condition actions. AD 2019-14-13 also provides an optional terminating action for the repetitive actions for certain seats. Since the FAA issued AD 2019- 14-13, the FAA has determined that additional seats are affected by the unsafe condition. This proposed AD would retain the actions required by AD 2019-14-13 and adds an inspection of previously omitted part numbers. The FAA is proposing this AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by October 24, 2024.
