Airworthiness Directives; British Aerospace Model Avro 146-RJ Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace Model Avro 146-RJ series airplanes, that requires a modification of the electrical system in the equipment bay area by replacing certain cables, clamps, and fairleads with new components. This amendment is prompted by a report indicating that the incorrect size of electrical cables were used in the generator feeder circuit to certain busbars from the generator contactors. As a result, the electrical cables are not compatible with generator rating requirements and can overheat. The actions specified by this AD are intended to prevent possible overheating of electrical generator feeder cables and consequent damage, which could lead to possible fire or the loss of essential electrical systems.
