## Abstract

This amendment adopts a new airworthiness directive (AD) applicable to Eurocopter France Model SA-360C, SA-365C, C1, and C2 helicopters. This action requires replacing certain electrical modules with airworthy electrical modules. This amendment is prompted by the discovery of several defective electrical modules. This condition if not corrected could result in loss of electrical continuity, which could cause loss of critical rotorcraft electrical systems and subsequent loss of control of the helicopter.
