EASA AD US-2025-11-05
Fuselage - Seat Track Splice Fittings - Inspection
Summary
The Federal Aviation Administration's Airworthiness Directive 2025-11-05 addresses certain Boeing Model 787-8, 787-9, and 787-10 airplanes. This directive requires inspection of seat track splice fittings due to reports that some fittings may have been manufactured with an incorrect titanium alloy material. The directive aims to ensure the structural integrity and safety of the aircraft cabin seating.
What Changed
This new airworthiness directive introduces mandatory inspections using X-ray fluorescence spectrometer or high frequency eddy current methods to verify the material of seat track splice fittings. It also specifies on-condition actions, including replacement of affected fittings. Additionally, an exception allowing the use of collar part number BACC30BS10K for certain tasks has been incorporated.
Why It Matters
This directive is critical for aviation professionals as it addresses a potential safety risk that could compromise emergency egress and structural response during emergency landings. Operators and maintenance teams must ensure compliance to prevent seat track failures that could cause serious injury to occupants. The directive also clarifies part equivalencies, aiding maintenance planning and parts procurement.
What To Do
Operators of Boeing 787-8, 787-9, and 787-10 airplanes must perform the required inspections within the compliance times specified in Boeing Alert Requirements Bulletin B787-81205-SB530086-00 RB, Issue 001, dated October 18, 2024. If incorrect materials are found, affected seat track splice fittings must be replaced. Compliance with this AD is mandatory by July 8, 2025.
