AD 2026-08-12 Airworthiness Directives; Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca, S.A.) Engines
Applicability*9
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) AD 2024-0202R1, dated September 8, 2025 (EASA AD 2024-0202R1).
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
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 2024-0202R1.
Unsafe condition
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, and the determination that certain serial numbers of the affected FCUs are not affected by the unsafe condition. The FAA is issuing this AD to detect and correct missing lubricating and balancing grooves on the bearings of the FCU fuel pump and reduce the number of affected serial numbers. The unsafe condition, if not addressed, could result in an uncommanded IFSD and a significant reduction of the control of a single engine helicopter.
Affected ADs
This AD replaces AD 2024-24-02, Amendment 39-22892 (89 FR 92789, November 25, 2024) (AD 2024-24-02).
