Airworthiness Directives; The Boeing Company Airplanes

The FAA is superseding Airworthiness Directive (AD) 2025-01- 06, which applied to all The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. AD 2025-01-06 required 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 2025-01-06 also required 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. Since the FAA issued AD 2025-01-06, the FAA determined that AD 2025-01-06 contains an error when providing conditions for taking credit using a previous revision of the service information. This AD requires the actions of AD 2025-01-06 and revises paragraph (j) of this AD to clarify which actions are not required. The FAA is issuing this AD to address the unsafe condition on these products.
