FAA Orders Helicopter Engine Bible Updates for Safety

## Summary

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.

## Effects PRIA read

- Must Revise Engine Maintenance Program: cost, low. If you operate a Safran Model Arriel 2E engine, you must revise your existing maintenance or inspection program to incorporate the airworthiness limitations section (ALS) from EASA AD 2025-0079. The AD is effective September 3, 2026, and you must incorporate the ALS actions, life limits, thresholds…
- Estimated Compliance Cost to Operators: cost, low. The FAA estimates this AD affects 136 engines on U.S. helicopters and that revising the ALS and approved AMP takes 1 work-hour at $85 per engine. The FAA estimates total cost to U.S. operators of $11,560 and calculates the cost per affected small entity at $85 (0.02% of average small-entity annual…
- Owner/Private Pilot May Perform Revision: benefit, low. The AD allows the owner/operator (pilot) holding at least a private pilot certificate to perform the required AMP/ALS revision and requires that the action be entered into the aircraft records per 14 CFR 43.9(a) and 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 121.38…
- AD Prevents Life-Limited Part Failures: benefit, high. The FAA issued this AD to prevent failure of life-limited parts on Safran Arriel 2E engines; if not addressed, the unsafe condition could result in failure of one or more engines, loss of thrust control, and reduced control of the helicopter. The AD requires replacing life-limited parts before exce…
