Summary
This document proposes the adoption of a new airworthiness directive (AD) applicable to Eurocopter France Model SA-365N, SA-365N1, and AS-365N2 helicopters. This proposal would require replacing certain defective electrical modules with airworthy electrical modules. This proposal is prompted by the discovery of several defective electrical modules. The actions specified by the proposed AD are intended to prevent loss of electrical continuity, which could cause loss of critical rotorcraft electrical systems and subsequent loss of control of the helicopter.
