What to do
Operators must identify Group 1 engines with affected parts installed and replace these parts within the compliance times specified in the directive or during the next piece-part exposure, whichever occurs first. Group 2 engines must not have affected parts installed from the effective date. Compliance involves following the instructions in the referenced CFM service bulletins and prohibiting reinstallation of affected parts.
Summary
EASA Airworthiness Directive 2023-0108 is issued for CFM International LEAP-1A engines installed on certain Airbus A319, A320, and A321 aircraft. It addresses the replacement of forward outer seals, high pressure compressor stages 6-10 compressor rotor spools, and high pressure turbine rotor stage 1 disks due to potential manufacturing defects. This directive mandates corrective actions to ensure continued airworthiness and prevent engine part failures.
What changed
This new Airworthiness Directive introduces mandatory replacement of affected engine parts that may contain iron inclusions resulting from manufacturing deficiencies. It prohibits the installation of these affected parts on any engine and requires operators to replace them within specified compliance times. The directive also references specific CFM service bulletins that provide detailed replacement instructions and affected part lists.
Why it matters
This directive is critical for aviation professionals as it addresses a potential unsafe condition that could lead to engine part failure and high-energy debris release, posing risks to aircraft safety and control. Operators and maintenance organizations must comply to avoid unplanned engine failures and ensure regulatory compliance. The directive also impacts inventory management by restricting the installation of affected parts.
