What to do
Operators of Airbus A380-841 and A380-842 aircraft must perform a general visual inspection of the ETRAS actuator fitting fire protection assemblies on engines #2 and #3 within 42 months from 29 April 2019. If sealant is found missing during the inspection, it must be applied before the next flight following Airbus Service Bulletin A380-78-8013 instructions. Alternative methods of compliance may be approved by EASA upon request.
Summary
EASA Airworthiness Directive 2019-0083 is an official safety directive addressing Airbus A380-841 and A380-842 aeroplanes equipped with Rolls-Royce Trent 900 engines. It mandates inspection of the electrical thrust reverser actuation system (ETRAS) actuator fitting fire protection assemblies on engines #2 and #3 to ensure proper sealing with silicone fire sealant. This directive aims to prevent potential fire hazards due to incomplete sealing of fire shields on the thrust reverser actuator fittings.
What changed
EASA Airworthiness Directive 2019-0083 introduces a one-time general visual inspection requirement for the affected fire protection assemblies on Airbus A380 aircraft. It requires operators to verify the presence of sealant material and apply it if missing, addressing a previously unidentified production issue where fire shields were not fully sealed. This directive does not supersede any previous ADs and is a new safety measure.
Why it matters
This directive is critical for aviation professionals as it mitigates the risk of uncontrolled fires caused by breaches in the firewall due to incomplete fire sealant application. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. Failure to comply could lead to serious safety incidents and regulatory non-compliance.
