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 replacing the existing roll spoiler control rods with improved parts. 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 bending stress to the fork end of the roll spoiler, which could result in failure of the roll spoiler and consequent reduced controllability of the airplane.
