Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A300 series airplanes; Model A300 B4-601, A300 B4-603, and A300 B4-622 airplanes; Model A300 B4-600R series airplanes; Model A300 C4-605R Variant F airplanes; and Model A300 F4-600R series airplanes. This proposed AD was prompted by reports of cracking of the main landing gear (MLG) two-piece cages due to incorrect machining. This proposed AD would require replacing an affected MLG with a serviceable MLG and would limit the installation of an affected MLG under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.
