EASA AD 2022-0083
SUPERSEDED BY EASA AD 2025-0079
Summary
EASA Airworthiness Directive 2022-0083 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting SAFRAN Helicopter Engines ARRIEL 2 series engines, including models 2D, 2E, 2H, 2L2, and 2N. These engines are commonly installed on helicopters such as Airbus Helicopters AS 350 B3 (H125), EC 130 T2 (H130), MBB-BK117 D-2 (EC 145 T2 or H145), Korea Aerospace Industries LAH and LCH, and AVIC AC312E. The directive mandates compliance with updated airworthiness limitations and maintenance tasks as specified in the latest SAFRAN ARRIEL 2 maintenance manuals.
What Changed
This directive supersedes EASA AD 2018-0273 and introduces new and/or more restrictive maintenance tasks and life limitations for the affected ARRIEL 2 engines. It requires operators to update their Aircraft Maintenance Programme to incorporate these latest tasks and thresholds as defined in the updated SAFRAN maintenance manuals dated December 2021. The directive retains previous requirements while mandating compliance with the revised airworthiness limitations.
Why It Matters
Compliance with EASA Airworthiness Directive 2022-0083 is critical to ensure the continued airworthiness and safety of helicopters powered by SAFRAN ARRIEL 2 engines. Operators, maintenance organizations, and compliance teams must adhere to the updated maintenance tasks and life limits to prevent unsafe conditions that could arise from overlooked or outdated procedures. This directive helps maintain regulatory compliance and reduces the risk of engine failures or malfunctions.
What To Do
Affected operators must replace engine components before exceeding their life limits and perform all maintenance tasks within specified intervals as detailed in the applicable SAFRAN ARRIEL 2 maintenance manuals. They must revise their approved Aircraft Maintenance Programme within 12 months of the directive's effective date to include the new or more restrictive tasks and limitations. Any discrepancies found during maintenance must be corrected according to SAFRAN-approved procedures before further flight.
