Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 and all Model A300-600 series airplanes. This proposal would require a one-time inspection for cracking of the gantry lower flanges in the main landing gear (MLG) bay area; and repair, 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 cracking of the gantry lower flanges in the MLG bay area, which could result in decompression of the airplane.
