The directive addresses a non-conformity involving electrical connectors installed under the lower fuselage fuel tank structure. It mandates rework and relocation of these connectors to ensure continued airworthiness and safety.
What changed
EASA Airworthiness Directive 2020-0004 introduces a mandatory modification requiring the relocation of affected electrical connectors and rework of certain structural parts under the lower fuselage fuel tank. This is to correct a discovered non-conformity that could lead to fuel tank damage in the event of a forced landing. The directive references Airbus Helicopters Alert Service Bulletin EC175-53A021 for detailed modification instructions.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk that could result in fuel tank damage and potential fire, endangering the helicopter and its occupants. Operators and maintenance organizations must comply to maintain aircraft airworthiness and avoid operational restrictions. Compliance ensures regulatory adherence and reduces the risk of costly incidents or accidents related to the affected connectors.
