Published Date: 8/6/2025
Rule
Summary
If you fly a Boeing 777, this update affects you! The FAA fixed a mistake in the old safety rules about checking the Captain’s and First Officer’s seats. You still need to inspect and monitor the seat parts, but now the instructions are clearer—keeping everyone safer without extra hassle or cost surprises.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
Boeing 777 seat inspections required
This rule replaces Airworthiness Directive (AD) 2024-15-03 for The Boeing Company Model 777 airplanes. It continues to require identifying the part numbers (and serial numbers, if applicable) of the Captain’s and First Officer’s seats and requires a one-time detailed inspection plus repetitive checks of the horizontal movement system (HMS) and any on‑condition actions specified in AD 2024-15-03.
Clarifies credit for prior service information
The FAA found an error in AD 2024-15-03 about taking credit for actions done using a previous revision of the service information. This superseding AD revises paragraph (j) to clarify which actions are not required when taking credit for a previous service-information revision.
