EASA AD 2024-0149
SUPERSEDED BY EASA AD 2026-0027
Summary
EASA Airworthiness Directive 2024-0149 is issued for SAFRAN Helicopter Engines ARRIUS 2B2 engines, which are commonly installed on Airbus Helicopters Deutschland EC135 and EC635 models. This directive mandates compliance with updated airworthiness limitations and maintenance tasks as specified in the latest Airworthiness Limitations Section of the ARRIUS 2B2 Maintenance Manual. It ensures continued airworthiness by enforcing life limits and maintenance intervals for engine components.
What Changed
EASA Airworthiness Directive 2024-0149 supersedes the previous AD 2022-0203 and introduces new and/or more restrictive maintenance tasks and life limits for ARRIUS 2B2 engines. These changes are reflected in the updated Chapter 05-10 Airworthiness Limitations Section of the engine maintenance manual, update no. 46. The directive retains previous requirements while incorporating these updated instructions.
Why It Matters
This directive is critical for aviation professionals as it mandates adherence to updated maintenance and life limit requirements to prevent unsafe conditions. Operators and maintenance organizations must ensure compliance to maintain engine airworthiness and avoid operational disruptions. It also streamlines compliance recording by allowing AMP revisions to demonstrate ongoing adherence to the AD.
What To Do
Operators must replace engine components before exceeding new life limits and perform all maintenance tasks within specified intervals as per the updated Airworthiness Limitations Section starting from 13 August 2024. Any discrepancies found during maintenance must be corrected before the next flight following SAFRAN instructions or approved alternatives. Additionally, the Aircraft Maintenance Programme must be revised within 12 months of the effective date to incorporate these updated limitations and tasks.
