Abstract
This amendment adopts a new airworthiness directive (AD), applicable to Eurocopter France Model AS 332C, L, L1, and L2 helicopters that requires replacing certain circuit breakers. This amendment is prompted by the manufacturer discovering, upon testing a circuit breaker installed in a helicopter, the loss of electrical continuity between the terminals of the installed circuit breaker. The actions specified by this AD are intended to prevent loss of electrical power caused by improper installation of certain circuit breakers, loss of electical power to instrumentation, and subsequent loss of control of the helicopter.
