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

This amendment adopts a new airworthiness directive (AD), applicable to all Dornier Model 328-100 and -300 series airplanes, that requires repetitive inspections of the bearing lugs of the rudder spring tab lever assembly for cracking, and corrective action if necessary. This action is necessary to prevent failure of the rudder flight control system due to such cracking, which could result in loss of rudder control and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
