What to do
Operators must replace all affected parts on Group 1 engines within specified compliance times or at the next piece-part exposure, whichever occurs first, following the instructions in the referenced CFM service bulletins. From the effective date, installation of any affected parts on any engine is prohibited. Compliance deadlines vary depending on part numbers and serial numbers, with some replacements required within 50 engine cycles after the directive's effective date of 11 November 2025.
Summary
EASA Airworthiness Directive 2025-0243 is an official regulatory document addressing the replacement of forward outer seals, high-pressure compressor stages 6-10 compressor rotor spools, and high-pressure turbine rotor stage 1 disks on CFM International LEAP-1A engines. These engines are commonly installed on Airbus A319, A320, and A321 aircraft. The directive mandates inspection and replacement of affected parts to ensure continued airworthiness and safety.
What changed
This directive supersedes EASA AD 2024-0225 and introduces additional affected parts identified by CFM International in their latest service bulletin issue. It retains previous replacement requirements and prohibits the installation of any affected parts on engines from the effective date. The update includes revised compliance times and expanded part number and serial number listings for replacement.
Why it matters
This AD addresses a critical safety concern involving iron inclusions found in certain engine parts, which can lead to premature failure and potentially hazardous high-energy debris release. Compliance is essential for operators and maintenance organizations to prevent engine failures and ensure regulatory adherence. The directive impacts maintenance planning, parts inventory management, and operational safety for affected Airbus aircraft powered by LEAP-1A engines.
