Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Dornier Model 328-100 and -300 series airplanes. This proposal would require a one-time inspection for fracture and/or breakage of the hinge bolt of the output rod of the rudder spring tab lever assembly, and corrective action if necessary. This proposal also would require modification of the hinge bolt. This action is necessary to prevent fracture and/or breakage of the hinge bolt, which could result in migration of the bolt tail, a loose spring tab, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
