SUPERSEDED BY EASA AD 2024-0161
Summary
EASA Airworthiness Directive 2022-0080 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A350-941 and A350-1041 aeroplanes with specific manufacturer serial numbers. The directive addresses an unsafe condition related to the centre wing box fasteners on these aircraft models. It mandates replacement of certain fasteners and the application of additional head nut cap protection to ensure continued airworthiness.
What Changed
This directive introduces a mandatory replacement of affected fasteners installed on the left-hand and right-hand centre wing box at the front and rear spar areas. It also requires the application of additional head nut cap protection as specified in Airbus Service Bulletin A350-57-P069. This is a new regulation aimed at correcting insufficient friction in fasteners that could lead to safety risks.
Why It Matters
This airworthiness directive is critical for aviation professionals as it addresses a potential safety hazard that could lead to fuel tank explosions in the event of a lightning strike. Operators, maintenance, repair, and overhaul (MRO) organizations must comply to prevent loss of fastener clamping and damage to nut sealant covers, thereby ensuring the structural integrity and safety of affected Airbus A350 aircraft. Compliance is essential to maintain regulatory approval for operation.
What To Do
Operators of affected Airbus A350-941 and A350-1041 aircraft must replace the specified centre wing box fasteners and apply additional head nut cap protection within 69 months from the effective date of 23 May 2022. The replacement and protection must be performed following the instructions in Airbus Service Bulletin A350-57-P069. Alternative methods of compliance may be approved by EASA if properly substantiated.
