What to do
Operators of affected Airbus A380 aircraft must apply the required sealant modification on the pylon box zone D within 42 months from the effective date of 30 October 2020. The modification must be performed following the instructions in the applicable Airbus Service Bulletins. Alternative methods of compliance may be approved by EASA if properly substantiated.
Summary
EASA Airworthiness Directive 2020-0225 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A380-841, A380-842, and A380-861 aeroplanes equipped with Rolls-Royce RB211 Trent 900 engines, except those with certain Airbus production modifications. The directive addresses sealing issues in the pylon box zone D to prevent potential fuel leakage. It mandates a modification to improve sealing performance on the pylon box to enhance safety.
What changed
This new airworthiness directive introduces a mandatory modification requiring the application of additional sealant on the top of each pylon box in zone D. The modification is based on Airbus Service Bulletins A380-54-8090 and A380-54-8091 and aims to correct a lack of sealant found during maintenance validation. No previous airworthiness directives are superseded by this AD.
Why it matters
This directive is critical for aviation professionals because it addresses a potential fuel leakage risk that could lead to fire or explosion, posing a serious safety hazard. Operators and maintenance organizations must ensure compliance to maintain the continuing airworthiness of affected Airbus A380 aircraft. Failure to comply could result in unsafe operating conditions and regulatory non-compliance.
