EASA AD 2018-0212R1
Powerplant — Engine Mount Titanium Crossbeam — Replacement [Life Limitation]
Summary
EASA Airworthiness Directive 2018-0212R1 is a regulatory document addressing the life limitation and replacement requirements for the forward engine mount titanium crossbeam, part number 238-0204-501, installed on Airbus A319-113, A319-114, A320-211, and A320-212 aeroplanes equipped with CFM56-5A engines. The directive mandates tracking the accumulated flight cycles of these crossbeams and replacing them before exceeding a life limit of 64,000 flight cycles to prevent potential failure and engine detachment in flight.
What Changed
This revision updates the original AD 2018-0212 by allowing the reinstallation of affected crossbeams with part number 238-0204-501 on any aeroplane, provided their accumulated life is below the 64,000 flight cycle limit. It clarifies installation rules and provides an alternative compliance method through modification with improved steel crossbeams, part number 642-2002-503.
Why It Matters
The directive is critical for operators and maintenance organizations to ensure the structural integrity of the engine mount crossbeam, preventing catastrophic engine detachment and ensuring continued airworthiness. Compliance with the life limits and replacement requirements reduces safety risks and aligns maintenance practices with regulatory standards.
What To Do
Operators must monitor the accumulated flight cycles of affected titanium crossbeams and replace them before reaching 64,000 flight cycles following Airbus Service Bulletin A320-71-1073. Alternatively, they may install improved steel crossbeams per Airbus Service Bulletin A320-71-1076. Installation of crossbeams with unknown life or unidentified part numbers is prohibited from 12 October 2018 onward.
