Краткое содержание

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