Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; and Airbus Model A300 B4-600, B4- 600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This proposed AD was prompted by reports of cracks in certain pins in the main landing gear (MLG). This proposed AD would require repetitive detailed visual inspections of the pins for cracks, and replacing the MLG leg if necessary. We are proposing this AD to detect and correct cracking of certain pins in the MLG, which could result in a MLG collapse, and consequent damage to the airplane and injury to the airplane occupants.
