Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes

概要

The FAA proposes to adopt a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This proposed AD was prompted by a report of an electrical contactor that failed with contacts in the intermediate position, causing the airplane to lose power to multiple electrical systems. This proposed AD would require repetitive operational tests of the affected part, and, depending on findings, accomplishment of applicable corrective action, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
