Airworthiness Directives; McDonnell Douglas Model MD-11 and -11F Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 and -11F airplanes, that requires installation of protective sleeving on the right emergency alternating current (AC) wire assembly of the overhead switch panel. This action is necessary to ensure that protective sleeving is installed on the right emergency AC wire assembly of the overhead switch panel. Lack of such sleeving could result in loss of redundant electrical power during certain cockpit overhead wiring faults. This action is intended to address the identified unsafe condition.
