Summary
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes. This proposed AD was prompted by our determination of the need to incorporate new life limits for the main landing gear (MLG) barrel assembly, retraction actuator assembly linkage, and flange duct. This proposed AD would require revising the maintenance or inspection program to include the new life limits. We are proposing this AD to prevent reduced structural integrity of the airplane and possible loss of controllability of the airplane.
