The FAA's summary their words, unchanged

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.

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2023-24-09 Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca, S.A.): Amendment 39-22626; Docket No. FAA-2023-1397; Project Identifier MCAI-2023-00014-E. (a) Effective Date This airworthiness directive (AD) is effective January 17, 2024. (b) Affected ADs None. (c) Applicability This AD applies to Safran Helicopter Engines, S.A. (type certificate previously held by Turbomeca S.A.) Model Arrius 2R engines. (d) Subject Joint Aircraft System Component (JASC) Code 7700, Engine Indicating System. (e) Unsafe Condition This AD was 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 or M02 modules installed on the engine. The FAA is issuing this AD to address inconsistencies between the TQ and MGT conformation values recorded. The unsafe condition, if not addressed, could result in reduced control of the helicopter due to one or more of the following: a power non-availability; a high-pressure blade rupture with consequent power loss and release of low-energy debris; or an overpassing of the helicopter transmission limit. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions 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). (h) Exceptions to 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. (i) No Reporting Requirement 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. (j) Alternative Methods of Compliance (AMOCs) (1) The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate.
