Summary
EASA Airworthiness Directive 2022-0203 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting SAFRAN Helicopter Engines ARRIUS 2B2 engines, commonly installed on Airbus Helicopters Deutschland EC135 and EC635 helicopters. The directive mandates compliance with updated airworthiness limitations and maintenance tasks as specified in the SAFRAN ARRIUS 2B2 Maintenance Manual Chapter 05-10 Airworthiness Limitations Section Temporary Update No. 05-9.
What Changed
This directive introduces new and/or more restrictive maintenance tasks and life limits for ARRIUS 2B2 engines, including reduced thresholds and intervals for certain components. It requires operators to replace components before exceeding life limits and to perform all applicable maintenance tasks within specified intervals. Additionally, it mandates updating the approved Aircraft Maintenance Programme to incorporate these changes within 12 months of the effective date.
Why It Matters
Compliance with EASA Airworthiness Directive 2022-0203 is critical to ensure the continued airworthiness and safety of helicopters equipped with ARRIUS 2B2 engines. Failure to follow the updated maintenance requirements could lead to unsafe conditions, potentially compromising flight safety. Operators, maintenance organizations, and compliance teams must integrate these changes to meet regulatory obligations and maintain operational approval.
What To Do
Operators must replace life-limited components before exceeding their new limits and perform all maintenance tasks as specified in the updated Airworthiness Limitations Section. They must revise the approved Aircraft Maintenance Programme to include these new tasks and limitations within 12 months from 14 October 2022. Any discrepancies found during maintenance must be addressed promptly according to SAFRAN-approved instructions, and compliance should be recorded through AMP revision.
