Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A320-200 series airplanes. This proposal would require modification of the shock absorber sub-assembly of the main landing gear (MLG). This proposal is prompted by reports of internal damage to the shock absorber sub- assembly due to loose screws in the upper bearing dowels. The actions specified by the proposed AD are intended to prevent such damage, which could result in the overextension of the shock absorber and failure of the torque link. This situation may lead to the inability of the MLG to retract and subsequent collapse of the MLG.
