EASA AD 2021-0085
Doors — Passenger Door Guide Arms — Replacement / Inspection / Modification
Summary
EASA Airworthiness Directive 2021-0085 is an airworthiness directive addressing the passenger door guide arms on Airbus A350-941 and A350-1041 aeroplanes. It focuses on the replacement, inspection, and modification of passenger door damper emergency opening actuators (DEOA) with part number FE396001001 to ensure safe emergency door operation.
What Changed
This directive supersedes EASA AD 2021-0018 and retains its requirements while introducing a modification that allows a maximum of one affected part per door pair to guarantee functionality. It mandates replacement of affected parts with serviceable parts and detailed inspections of guide arm support brackets following door emergency openings.
Why It Matters
The directive addresses a safety concern where oil leakage in the DEOA could cause excessive door opening speed, potentially leading to door failure during emergencies. Compliance ensures continued airworthiness, reduces risk of evacuation delays, and prevents injury to occupants, which is critical for operators, maintenance organizations, and regulatory compliance teams.
What To Do
Operators must replace forward and aft guide arms within specified timeframes after door emergency openings and perform detailed inspections of support brackets. Damaged parts must be repaired or replaced before further flight. Additionally, aeroplanes must be modified within 32 months to limit affected parts per door pair, and installation of affected parts is restricted from the effective date.
