Airworthiness Directives; Dornier Model 328-100 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires an inspection of the alternating current (AC) power cables, realignment of the AC power cable retaining clamp, and corrective actions if necessary. This action is necessary to prevent chafing of the AC power cables against the alternator, which could result in a short circuit and impaired performance of AC-powered components, possibly leading to loss of flight-critical information to the flight deck and reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
