Airworthiness Directive · Amendment 39-10583 · Lucas Air Equipment Electric Hoists
Lucas Air Equipment Electric Hoists
Electric hoists, part numbers (P/N) 76375-030, 76375-130, 76378, or 76378-100, equipped with electronic control boxes, P/N 61148-001, 002, or 006, installed on, but not limited to all models of Eurocopter France SA-360 and SA-365 helicopters, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to Lucas Air Equipment electric hoists (hoists) installed on, but not limited to, all models of Eurocopter France SA-360 and SA- 365 helicopters that requires visually inspecting the cable for damage before the next hoist operation, blanking (plugging) the electronic control box upper vent, and performing an end-of-travel procedure before each hoist operation. This amendment is prompted by several incidents of cable failures caused by dynamic overload on the winding- up limit due to uncontrolled excessive speed of the cable, which is normally regulated by the automatic speed-reducing mechanism or the operator. The actions specified by this AD are intended to prevent breaking of the cable, which could become entangled with a main rotor or tail rotor blade, and result in damage or separation of a rotor blade, and subsequent loss of control of the helicopter.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
