Airworthiness Directive · Amendment 39-22847 · Engine
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 Makila 1A, Makila 1A1, and Makila 1A2 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 Makila 1A, Makila 1A1, and Makila 1A2 engines. This AD is prompted by a determination that the accumulated service life of certain critical parts was underestimated. This AD requires determining the recalculated service life of certain critical parts, replacing if necessary, and also specifies conditions for installing the parts, 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 paragraph (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2023-0218, dated December 19, 2023 (EASA AD 2023-0218).
(1) Where EASA AD 2023-0218 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where the service information referenced in EASA AD 2023-0218 specifies to return certain parts to the manufacturer, this AD requires removing those parts from service.
(3) This AD does not adopt the Remarks paragraph of EASA AD 2023-0218.
(4) Where the service information referenced in EASA AD 2023-0218 specifies contacting the manufacturer for additional cycles for certain parts, this AD requires contacting the Manager, International Validation Branch, FAA, for additional cycles for certain parts, if those parts are installed on aircraft of U.S. Registry.
Although the service information referenced in EASA AD 2023-0218 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
