## Summary

We propose to supersede Airworthiness Directive (AD) 99-16-01, for certain 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). AD 99-16-01 currently requires repetitive inspections of certain bolt holes where parts of the main landing gear (MLG) are attached to the wing rear spar, and repair if necessary. Since we issued AD-99-16-01, we have determined that the risk of cracking in the rear spar is higher than initially determined. This proposed AD would add airplanes to the applicability, reduce the compliance times and repetitive intervals for the inspections, and change the inspection procedures. We are proposing this AD to detect and correct cracking of the rear spar of the wing, which could result in reduced structural integrity of the airplane.
