Airworthiness Directive · Amendment 39-22626 · Engine indicating system
Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca S.A.) Engines
This AD applies to Safran Helicopter Engines, S.A. (type certificate previously held by Turbomeca S.A.) Model Arrius 2R engines.
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.
Except as specified in paragraphs (h) and (i) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2022-0265R1, dated January 6, 2023 (EASA AD 2022-0265R1).
(1) Where EASA AD 2022-0265R1 refers to January 4, 2023 (the effective date of the original issue of EASA AD 2022-0265), this AD requires using the effective date of this AD.
(2) This AD does not adopt the Remarks paragraph of EASA AD 2022-0265R1.
Although the service information referenced in EASA AD 2022-0265R1 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
