## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2019-03-10, which applies to all Airbus SAS Model A300 series airplanes; and 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). AD 2019-03-10 requires repetitive detailed visual inspections of the main landing gear (MLG) leg components and replacement of the MLG leg if cracked components are found. Since the FAA issued AD 2019-03-10, it was determined that additional actions (including inspections, modifications, and checks) are needed to address the unsafe condition. This proposed AD would continue to require the actions required by AD 2019-03-10. For certain airplanes, this proposed AD would also require modification of the MLG hinge arm by installing improved MLG hinge arm/barrel pins; an out-of- roundness check of removed pins; repetitive inspections of any affected pins and the associated connecting rod bushes,and replacement of the MLG leg if cracked components are found; and installation of an improved spacer as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
