EASA AD 2025-0210
Wings — Centre Wing Box Fasteners — Replacement
Summary
EASA Airworthiness Directive 2025-0210 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A350-941 aeroplanes with specific manufacturer serial numbers. The directive addresses the replacement of centre wing box fasteners and the application of additional head nut cap protection to ensure continued airworthiness.
What Changed
This new airworthiness directive introduces a requirement to replace certain fasteners on the left-hand and right-hand sides of the centre wing box that may have been installed without proper double overcoating sealant or are susceptible to rotation. It also mandates the application of additional head nut cap protection to mitigate the risk of fastener clamping loss and potential fuel tank explosion in case of lightning strike.
Why It Matters
This directive is critical for aviation professionals because it addresses a potential unsafe condition that could lead to structural failure and increased risk of fuel tank explosion. Operators and maintenance organizations must ensure compliance to maintain aircraft safety and regulatory approval, avoiding operational disruptions and potential safety incidents.
What To Do
Operators of affected Airbus A350-941 aeroplanes must replace the specified centre wing box fasteners and apply additional head nut cap protection within 78 months from the effective date of 8 October 2025. Compliance must follow the instructions detailed in Airbus Service Bulletin A350-57-P094 or its later approved revisions.
