## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires modification of the electrical circuits for certain avionics by rewiring and adding electrical devices. This amendment is prompted by reports indicating that failure of an engine or direct current (DC) generator during takeoff and landing, coupled with an open DC tie, could cause the avionics to fail. The actions specified by this AD are intended to prevent the failure of those avionics during takeoff and landing, which consequently could result in the inability of the flight crew to respond to and control the associated systems during these critical phases of flight.
