What it does

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.
