Airworthiness Directive · Amendment 39-22892 · Engine fuel pump
Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca S.A.)
This AD applies to Safran Helicopter Engines, S.A. (type certificate previously held by Turbomeca S.A.) Model ARRIUS 2F engines, as identified in European Union Aviation Safety Agency (EASA) Emergency AD 2024-0202-E, dated October 22, 2024 (EASA AD 2024-0202-E).
The FAA is adopting a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2F engines. This AD was prompted by a report of an uncommanded in-flight shut-down (IFSD) of a Safran Model ARRIUS 2F engine, followed by an investigation that revealed the IFSD was due to a missing lubricating and balancing groove on one of the bearings of the fuel control unit (FCU) fuel pump related to a non-conforming manufacturing process. This AD requires removal of the affected fuel pump from service and replacement with a serviceable part, 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: Do all required actions within the compliance times specified in, and in accordance with EASA AD 2024-0202-E.
(1) Where EASA AD 2024-0202-E requires compliance from its effective date, this AD requires using the effective date of this AD.
(2) This AD does not adopt the “Remarks” section of EASA AD 2024-0202-E.
(3) Although the service information referenced in EASA AD 2024-0202-E specifies to return the FCU to a Repair Center approved by Safran Helicopter Engines, this AD requires removing those parts from service.
Although the service information referenced in EASA AD 2024-0202-E specifies to submit certain information to the manufacturer, this AD does not include that requirement.
