Airworthiness Directives; Airbus Model A300 and A300-600 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300 and all Model A300-600 series airplanes, that requires a one-time inspection for cracking of the gantry lower flanges in the main landing gear (MLG) bay area; and repair, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this 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.
