Airworthiness Directives; Dornier Model 328-100 and -300 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 and -300 series airplanes, that requires inspection of the nose landing gear (NLG) and main landing gear (MLG) to ensure that certain bolts are in place; repetitive inspections of the bolts and bolt areas for evidence of corrosion; and corrective action, if necessary. This action is necessary to prevent failure of the NLG or MLG due to corroded or missing bolts, which could cause loss of connection pins, and consequent collapse of the landing gear during ground maneuvers or upon landing. This action is intended to address the identified unsafe condition.
