EASA AD 2024-0133R1
Time Limits / Maintenance Checks — Airworthiness Limitations Section — Amendment
Summary
EASA Airworthiness Directive 2024-0133R1 is an amendment addressing the Airworthiness Limitations Section for Airbus Helicopters AS 350 B, BA, BB, B1, and D models. It updates maintenance tasks and life limits as specified in the Airbus Helicopters AS 350 Aircraft Maintenance Manual Chapter 04, Revision 009. This directive ensures continued airworthiness by mandating compliance with updated maintenance requirements.
What Changed
This amendment revises the original EASA AD 2024-0133 by removing AS 350 B2, B3, EC 130 B4, and EC 130 T2 helicopters from its applicability, as those models are now covered under a separate AD 2025-0137. It incorporates new and more restrictive maintenance tasks and life limits introduced in the latest ALS Revision 009 for the remaining AS 350 helicopter models.
Why It Matters
This directive is critical for operators and maintenance organizations to maintain the safety and airworthiness of affected AS 350 helicopters. It consolidates and updates mandatory maintenance tasks and life limits, reducing the risk of unsafe conditions due to component failures. Compliance ensures regulatory adherence and helps prevent operational disruptions caused by unaddressed maintenance requirements.
What To Do
Operators must replace components before exceeding life limits and perform all maintenance tasks within specified intervals as per ALS Revision 009 starting from 17 July 2024. They must revise their approved Aircraft Maintenance Programme within 12 months of that date to incorporate these updated limitations and tasks. Any discrepancies found during maintenance require corrective actions before the next flight or within specified compliance times.
