## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) for all Airbus Model A300 B4-601, A300 B4-603, A300 B4-620, A300 B4-605R, A300 B4-622R, and A300 F4-605R airplanes. That AD currently requires repetitive inspections for cracking in the area surrounding certain fuselage attachment holes, installation of new fasteners for certain airplanes, and certain follow-on corrective actions if necessary. This proposed AD would require modifying certain fuselage frames, which would terminate certain repetitive inspections. This proposed AD would also add airplanes to the applicability. This proposed AD is prompted by the development of a modification intended to prevent cracking of the center section of the fuselage, which could result in a ruptured frame foot and reduced structural integrity of the airplane.
