Airworthiness Directives; Boeing Model 767-400ER, 777-200, and 777-300 Series Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-400ER, 777-200, and 777-300 series airplanes. This AD requires replacing, with new parts, the existing tie-down fitting studs that secure galleys, purser work stations, and closets to the seat tracks. This AD is prompted by a report that tie-down fitting studs were found damaged. We are issuing this AD to prevent a galley, purser work station, or closet from detaching from the tie-down fitting studs during an emergency landing, which could injure passengers or crewmembers, or obstruct escape routes and impede emergency evacuation.
