Description
The FAA proposes a new airworthiness directive (AD) for all Airbus SAS Model A300 series airplanes, including various sub-models. This AD is prompted by reports of cracking in the main landing gear (MLG) two-piece cages due to incorrect machining. The directive would require replacing affected MLGs with serviceable ones and limit the installation of affected MLGs under certain conditions to address the unsafe condition. Comments on this proposed AD must be received by November 6, 2026.
