EASA AD US-2025-20-14
Equipment / Furnishings - IPECO 3A090 and 3A258 Flight Crew Seats - Inspection
Summary
The Equipment / Furnishings - IPECO 3A090 and 3A258 Flight Crew Seats - Inspection is a Federal Aviation Administration (FAA) Airworthiness Directive (AD 2025-20-14) that applies to all Boeing 757-200 series airplanes. It addresses uncommanded movement issues in the Captain's and First Officer's seats equipped with Ipeco 3A090 and 3A258 flight crew seats. The AD mandates inspections and maintenance actions to ensure seat safety and airplane controllability.
What Changed
This AD supersedes AD 2018-26-03 by retaining its requirements and adding inspections for previously omitted seat part numbers. It clarifies applicability to seats currently installed on airplanes and updates acceptable compliance conditions to include additional Boeing and Ipeco service bulletins. Corrections to service bulletin references and inclusion of new service information were also made based on stakeholder feedback.
Why It Matters
This AD is critical for aviation professionals because uncommanded seat movement can compromise pilot control and overall flight safety. Operators, maintenance, and compliance teams must ensure that affected seats are inspected and maintained according to the updated requirements to prevent potential accidents. The directive also provides clear guidance on acceptable compliance methods, reducing ambiguity and ensuring consistent safety standards.
What To Do
Operators must perform repetitive inspections and checks of the horizontal movement system (HMS) on the Captain's and First Officer's seats, including newly identified seat part numbers. Compliance with the AD is mandatory by January 2, 2026. Operators should review airplane records to determine if previous service bulletin actions satisfy the AD requirements and follow the specified inspection and maintenance procedures accordingly.
