The FAA's summary their words, unchanged
The FAA is superseding Airworthiness Directive (AD) 2024-24-02 for all Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2F engines. AD 2024-24-02 required removal of the affected fuel control unit (FCU) from service and replacement with a serviceable part. Since the FAA issued AD 2024-24-02, it was determined that certain serial numbers of the affected FCUs are not subject to the unsafe condition. This AD requires removal of the affected FCU from service and replacement with a serviceable part. This AD also reduces the number of affected FCUs. 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: a. Removing Airworthiness Directive 2024-24-02, Amendment 39-22892 (89 FR 92789, November 25, 2024); and b. Adding the following new airworthiness directive: 2026-08-12 Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca, S.A.): Amendment 39-23320; Docket No. FAA-2026-0016; Project Identifier MCAI-2025-01450-E. (a) Effective Date This airworthiness directive (AD) is effective June 2, 2026. (b) Affected ADs This AD replaces AD 2024-24-02, Amendment 39-22892 (89 FR 92789, November 25, 2024) (AD 2024-24-02). (c) Applicability 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). (d) Subject Joint Aircraft System Component (JASC) Code 7314, Engine Fuel Pump. (e) 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. (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: Do all required actions within the compliance times specified in, and in accordance with EASA AD 2024-0202R1. (h) Exceptions to EASA AD 2024-0202R1 (1) Where EASA AD 2024-0202R1 refers to "October 24, 2024 [the effective date of the original issue of this AD]," this AD requires using December 10, 2024 (the effective date of AD 2024-24-02). (2) Although the service information referenced in EASA AD 2024-0202R1 specifies to return the FCU to a Repair Center approved by Safran Helicopter Engines, this AD requires removing those parts from service. (3) This AD does not adopt the "Remarks" section of EASA AD 2024-0202R1. (i) No Reporting Requirement Although the service information referenced in EASA AD 2024-0202R1 specifies to submit certain information to the manufacturer, this AD does not include that requirement. (j) Alternative Methods of Compliance (AMOCs) 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.
