## Abstract

This amendment adopts a new airworthiness directive (AD) for Eurocopter France (ECF) Model AS-365N3 helicopters that requires modifying the Full Authority Digital Engine Control (FADEC) software within 90 days after the effective date of this AD. This amendment is prompted by a design problem in the FADEC "power loss printed circuit board" software found during laboratory testing. The actions specified by this AD are intended to prevent loss of the FADEC one-engine- inoperative power and subsequent loss of control of the helicopter.
