Краткое содержание

This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters with a Breeze 300-pound electric hoist (hoist) installed that requires modifying and re-identifying the hoist operator control unit and replacing certain fuses. This amendment is prompted by a test of a hoist that revealed an anomaly in the electrical control circuit. The actions specified by this AD are intended to prevent failure of the hoist pyrotechnic squib electrical control unit, lack of adequate current to activate the hoist pyrotechnic squib, an inability of the pilot to cut the rescue hoist cable in the event of cable entanglement or other emergency, and subsequent loss of control of the helicopter.
