What the agency says
The FAA is superseding Airworthiness Directive (AD) 2024-15- 03, which applied to all The Boeing Company Model 777 airplanes. AD 2024-15-03 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 2024-15-03 also required a one-time detailed inspection and repetitive checks of the horizontal movement system (HMS) for the Captain's and First Officer's seats and applicable on-condition actions. Since the FAA issued AD 2024-15-03, the FAA determined that AD 2024-15-03 contains an error when providing conditions for taking credit using a previous revision of the service information. This AD requires the actions of AD 2024-15-03 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.
