EASA AD 2022-0007
Time Limits / Maintenance Checks — Airworthiness Limitations Section — Implementation
Summary
EASA Airworthiness Directive 2022-0007 is an airworthiness directive addressing the LEAP-1A series engines manufactured by CFM International, installed on Airbus A319, A320, and A321 aircraft. It mandates compliance with updated airworthiness limitations and maintenance checks as specified in the LEAP-1A Engine Shop Manual Chapter 05 and related service bulletins. The directive applies to various LEAP-1A engine models and specific life-limited parts identified by part and serial numbers.
What Changed
This directive introduces new and more restrictive life limits and maintenance tasks for certain LEAP-1A engine parts, including compressor rotor spools and turbine disks, due to identified material anomalies that could reduce part life capability. It requires operators to replace affected components before exceeding these updated life limits and to perform maintenance tasks within specified intervals. Additionally, it mandates revising the Aircraft Maintenance Programme to incorporate these updated tasks and limitations within 12 months of the effective date.
Why It Matters
The directive is critical for aviation professionals because failure to comply with the updated life limits and maintenance tasks could lead to part failures, potentially causing high-energy debris release and reduced aircraft control. Operators and maintenance organizations must ensure continued airworthiness by adhering to these mandatory instructions to prevent unsafe conditions. Compliance ensures regulatory adherence under EU regulations and maintains aircraft safety and operational reliability.
What To Do
Affected operators must replace life-limited parts before exceeding the new life limits and perform all required maintenance tasks within the specified thresholds and intervals starting from 2 February 2022. They must revise their Aircraft Maintenance Programme within 12 months after the effective date to include the updated tasks and limitations. In case of discrepancies found during maintenance, corrective actions must be taken promptly according to CFM maintenance documentation or with approved instructions from CFM if existing guidance is insufficient.
