Airworthiness Directive 2023-27257
one-timeAirworthiness Directives; Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca S.A.) Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A. (Safran) (type certificate previously held by Turbomeca S.A.) Model Arrius 2R engines. This AD is prompted by reports of inconsistencies between the torque (TQ) and measured gas temperature (MGT) conformation values recorded in the avionics and the TQ and MGT conformation values recorded on the engine log cards following replacement of the M01 and M02 modules installed on the engine. This AD requires a one-time check of the consistency between the TQ and MGT conformation values recorded in the avionics and the values recorded on the engine log cards, and, if necessary, recalibrating the values and updating the engine logs, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2023-27257 applies to
Type certificate previously held by Turbomeca S.A.
Whether AD 2023-27257 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
