Summary
<RM>This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A330 and A340 series airplanes. This proposal would require installation of a retainer device on the attachment pin of the brake torque rod of the main landing gear (MLG). This action is necessary to prevent the attachment pin from fully migrating from the brake torque rod and to prevent the collar from detaching from the MLG; these conditions could result in loss of braking on two wheels and the inability to extend the MLG. This action is intended to address the identified unsafe condition.
