## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to Eurocopter France Model SA-360C, SA-365C, C1, C2, SA-365N, N1, AS-365N2, and SA-366G1 helicopters. This proposal would require inspecting and, if necessary, replacing certain circuit breakers. This proposal is prompted by the manufacturer discovering the loss of electrical continuity between the terminals of a circuit breaker. The actions specified by the proposed AD are intended to prevent loss of electrical power, loss of instrumentation, and subsequent loss of control of the helicopter.
