## Summary

The Federal Aviation Administration (FAA) proposes to adopt a new airworthiness directive (AD) that is applicable to Turbomeca S.A. Arrius-2F turboshaft engines with certain serial number (SN) Fuel Control Units (FCU's). This proposal would require adjusting the FCU maximum fuel flow mechanical stop position to a higher fuel flow setting. This proposal is prompted by an FCU discovered to have a maximum fuel flow limit adjusted below the maximum required setting. The actions specified by the proposed AD are intended to prevent reduced maximum available power during takeoff, landing, or an emergency, which could significantly affect helicopter performance and result in loss of the helicopter.
