What to do
Operators of affected Airbus A318, A319, A320, and A321 aircraft must replace any affected forward engine mount main beam assemblies within 72 months, 10,000 flight cycles, or 15,000 flight hours from 10 August 2017, whichever occurs first. Installation of affected parts is prohibited after the compliance deadline or after modification. Maintenance teams should follow the instructions in Airbus Service Bulletins A320-71-1065 and A320-71-1066 and Goodrich Aerospace SB RA32071-159 for inspections and replacements.
Summary
EASA Airworthiness Directive 2017-0132R2 is an updated regulatory requirement addressing the replacement of forward engine mount main beam snouts on Airbus A318, A319, A320, and A321 aircraft equipped with CFM56-5A and CFM56-5B engines. The directive targets specific part numbers 642-2006-501 and 642-2006-503 of the forward engine mount main beam assemblies due to potential wear issues that could lead to engine detachment. It mandates inspections and replacement actions to ensure continued airworthiness and safety.
What changed
This revision extends the calendar compliance time for replacing affected forward engine mount main beams and updates the document to align with the latest AD writing standards. It does not alter the core requirements but provides editorial improvements and clarifications. The directive supersedes the previous revision 2017-0132R1.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk that could result in in-flight engine detachment, potentially compromising aircraft control and safety on the ground. Operators and maintenance organizations must ensure compliance to prevent hazardous failures and maintain regulatory conformity. Timely replacement of affected parts reduces the risk of catastrophic engine mount failure.
