## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires replacement of the main landing gear (MLG) uplocks with new or modified MLG uplocks. This amendment is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent failure of the MLG to lock in the stowed position due to ice accumulation on the uplock hook and roller assembly, which could result in the inadvertent deployment of the MLG during flight.
