## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires repetitive inspections of certain support arms of the ground spoiler assemblies for cracking, and replacement of any ground spoiler assembly having cracking with a new ground spoiler assembly. This amendment would also require certain inspections for discrepancies of the ground spoiler assemblies and the flap of each wing; and corrective actions if necessary. This action is necessary to prevent failure of the support arms due to cracking, which could result in loss of function and/or separation of the affected ground spoiler assemblies from the airplane, and consequent reduced controllability of the airplane during landing or rejected take-off operations. This action is intended to address the identified unsafe condition.
