## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires a one-time inspection to measure the offset of the de-icing tubing adjacent to the refueling panel on the right-hand wing, and replacement with new improved tubing, if necessary. 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 a blockage in the de-icing tubing which could result in a malfunction of the de-icing boot. This malfunction would be unknown to the flight crew, and could lead to reduced controllability of the airplane during flight in icing conditions.
