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 modification of the ground cooling fan. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent failure of the ground cooling fan, which could result in smoke in the flight deck and cabin and consequent inability of the flight crew to perform duties or possible passenger injury due to smoke inhalation.
