## Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300-600 series airplanes. This proposed AD was prompted by reports of cracking found in the pylon box, which was due to the stresses resulting from the pressure applied by the engines' thrust reverser cowl bumpers. This proposed AD would require repetitive high frequency eddy current (HFEC) inspections for cracking, and replacement of all fittings if necessary. Replacement of all fittings would terminate the repetitive HFEC inspections. We are proposing this AD to detect and correct cracks of the pylon rib 5, which could result in reduced structural integrity of the airplane.
