EASA AD 2022-0133
Powerplant — Engine Inlet Attach Fittings — Replacement
Summary
EASA Airworthiness Directive 2022-0133 is an airworthiness directive addressing corrosion and cracking issues in engine inlet attach fittings on Airbus A330-201, A330-202, A330-203, A330-301, A330-302, and A330-303 aeroplanes. The directive mandates inspection and replacement of affected engine inlet attach fittings made of specific aluminum alloys to ensure continued airworthiness. It applies to all manufacturer serial numbers of the specified Airbus A330 models.
What Changed
EASA Airworthiness Directive 2022-0133 introduces a new requirement for a one-time inspection of engine inlet attach fittings to detect corrosion and cracks, followed by replacement of affected parts with serviceable ones. It prohibits installation of affected parts from the effective date and allows replacement of the entire inlet cowl as a compliance method. This is a new regulation addressing stress corrosion cracking susceptibility in certain aluminum alloy fittings.
Why It Matters
This directive is critical for aviation professionals because undetected corrosion or cracking in engine inlet attach fittings can lead to fitting failure, potentially causing damage to the aircraft and risking occupant safety. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and avoid operational disruptions. Compliance teams must track inspection deadlines and part replacements to meet regulatory requirements.
What To Do
Operators must inspect each engine inlet attach fitting within a compliance timeframe based on the inlet's time in service, ranging from 3 to 6 years after the directive's effective date of 2022-07-19. If affected parts are found, they must be replaced with serviceable parts before the next flight. Installation of affected parts is prohibited from the effective date onward, and replacing the inlet cowl with one free of affected parts is an acceptable alternative.
