EASA AD 2024-0150
Time Limits / Maintenance Checks — Airworthiness Limitations Section — Amendment
Summary
EASA Airworthiness Directive 2024-0150 is an amendment addressing the time limits and maintenance checks in the Airworthiness Limitations Section for SAFRAN Helicopter Engines ARRIUS 2K2 engines, commonly installed on Leonardo A109 helicopters. This directive mandates compliance with updated maintenance tasks and life limits as specified in the latest SAFRAN Arrius 2K2 Maintenance Manual. It ensures continued airworthiness by enforcing new or more restrictive maintenance requirements.
What Changed
EASA Airworthiness Directive 2024-0150 introduces new and/or more restrictive maintenance tasks and reduced life limits for components as defined in the latest update (no. 42) of the Airworthiness Limitations Section of the SAFRAN Arrius 2K2 Maintenance Manual. These changes replace previous maintenance requirements and must be incorporated into the Aircraft Maintenance Programme within 12 months of the effective date.
Why It Matters
This directive is critical for operators and maintenance organizations to prevent unsafe conditions by ensuring that all updated maintenance tasks and life limits are followed. Non-compliance could lead to operating engines beyond safe limits, risking engine failure and compromising flight safety. It also provides a clear framework for recording compliance and updating maintenance programs to meet regulatory standards.
What To Do
Operators of Leonardo A109 helicopters with ARRIUS 2K2 engines must replace components before exceeding new life limits and perform all updated maintenance tasks within specified intervals starting from 13 August 2024. They must revise their Aircraft Maintenance Programme to incorporate these changes within 12 months of the effective date. Any discrepancies found during maintenance must be corrected before the next flight, following SAFRAN instructions or contacting SAFRAN if no instructions exist.
