Airworthiness Directives; Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca, S.A.) Engines
Key claim: The FAA is issuing a new airworthiness directive requiring operators of Safran Arriel 2E helicopter engines to revise their maintenance or inspection programs to incorporate more restrictive airworthiness limitations.
Abstract
(Rule · Transportation Department, Federal Aviation Administration) The FAA is adopting a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A. (Safran) Model Arriel 2E engines. This AD was prompted by the determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program to incorporate the airworthiness limitations section (ALS) of the existing approved aircraft maintenance program (AMP), as applicable. The FAA is issuing this AD to address the unsafe condition on these products.
Why this matters
This AD extends the pattern of engine-specific airworthiness limitations updates seen across Safran/Turbomeca and Rolls-Royce helicopter engines, tightening life-limited part and maintenance task requirements for the Arriel 2E used in twin-engine helicopters. Operators must incorporate the more restrictive limits into their approved maintenance programs, with practical effects on inspection intervals and part retirement timelines.
