## Summary

We propose to supersede Airworthiness Directive (AD) 95-18-08, for all Airbus Model A300-600 series airplanes. AD 95-18-08 currently requires repetitive inspections to detect cracks in the bottom skin of the wing in the area of the cut out for the pylon rear attachment fitting, and repair if necessary. Since we issued AD 95-18-08, we received a report that updated fatigue and damage tolerance analyses and a fleet survey found that certain inspection thresholds and intervals must be reduced to allow more timely findings of cracking. This proposed AD would, for certain airplanes, reduce the compliance times for the inspections. We are proposing this AD to detect and correct such fatigue-related cracking, which could result in reduced structural integrity of the wing.
