Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Dornier Model 328-100 series airplanes. This proposal would require replacement of the main landing gear (MLG) uplocks with new or modified MLG uplocks. This proposal is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed 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.
