EASA AD 2020-0250
Powerplant — Engine Mount Shackle — Replacement
Summary
EASA Airworthiness Directive 2020-0250 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A319, A320, and A321 aeroplanes with specific forward engine mount shackle assemblies. It addresses potential premature wear and failure of the forward engine mount shackles, which could lead to engine detachment in flight. The directive applies to certain part numbers of engine mount shackles and requires replacement with serviceable parts.
What Changed
EASA Airworthiness Directive 2020-0250 introduces a mandatory replacement of affected forward engine mount shackle assemblies on Airbus A319, A320, and A321 aircraft before they accumulate 9,400 flight cycles. It also allows installation of affected parts only if they have not exceeded this flight cycle limit and mandates concurrent re-identification of engine mounts. This is a new regulation addressing a specific unsafe condition identified during fatigue testing.
Why It Matters
This directive is critical for aviation professionals as it prevents potential engine mount failure that could result in in-flight engine detachment, posing serious safety risks. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and avoid operational disruptions. Compliance teams need to track affected parts and flight cycles to meet regulatory requirements and ensure continued safe operation.
What To Do
Operators of affected Airbus A319, A320, and A321 aeroplanes must replace any affected forward engine mount shackle assemblies before they reach 9,400 flight cycles since first installation. If the flight cycles are unknown, guidance on traceability should be used to determine compliance. Installation of affected parts is allowed only under specific conditions, and all replacements must follow Airbus Component Service Bulletin A320ENGMOUNT-71-1087 instructions.
