<HD SOURCE="HED">SUMMARY:</HD>
The FAA is adopting a new airworthiness directive (AD) for certain ATR—GIE Avions de Transport Régional Model ATR42 and ATR72 airplanes. This 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 AD requires 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 incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
