What to do
Operators with Group 1 engines containing affected parts must replace these parts within the compliance time specified in the CFM Service Bulletin or at the next engine shop visit, whichever occurs first, after 1 July 2022. Installation of affected parts is prohibited on all engines from the effective date. Compliance with the CFM Service Bulletin instructions is required.
Summary
EASA Airworthiness Directive 2022-0113 is an airworthiness directive addressing CFM International LEAP-1A engines installed on certain Airbus A319, A320, and A321 aircraft. It mandates the replacement of specific compressor rotor spools (Stages 6-10) and high pressure turbine rotor stage 1 disks identified as affected parts due to potential manufacturing defects. The directive aims to ensure continued airworthiness and prevent engine part failure.
What changed
This new airworthiness directive introduces mandatory replacement of affected compressor rotor spools and high pressure turbine rotor disks that may contain iron inclusions from manufacturing deficiencies. It prohibits installation of these affected parts on any engine and requires compliance within specified cycles or at the next engine shop visit after the effective date.
Why it matters
This directive is critical for aviation professionals because iron inclusions in these engine parts can reduce mechanical properties and lead to premature failure, risking high energy debris release and potential loss of aircraft control. Operators and maintenance organizations must ensure affected parts are replaced promptly to maintain safety and regulatory compliance.
