Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Airbus Model A330 and A340 series airplanes. This proposal would require repetitive ultrasonic inspections to detect corrosion of the retraction links of the main landing gear (MLG), and replacement of the retraction link with a new retraction link, if necessary. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to detect and correct corrosion of the retraction link of the MLG, which could result in reduced structural integrity and possible collapse of the MLG.
