## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A300-600 series airplanes. The existing AD currently requires repetitive eddy current inspections to detect cracks of the outer skin of the fuselage at certain frames, and repair or reinforcement of the structure at the frames, if necessary. The existing AD also requires eventual reinforcement of the structure at certain frames, which, when accomplished, terminates the repetitive inspections. This proposed AD would add, for airplanes that were previously reinforced but not repaired in accordance with the existing AD, a one-time inspection for cracking of the fuselage outer skin at frames 28A and 30A above stringer 30, and repair if necessary. This proposed AD results from a report that the previously required actions were not sufficient to correct cracking before the structural reinforcement was installed. We are proposing this AD to prevent such fatigue cracking, whichcould result in reduced structural integrity, and consequent rapid decompression of the airplane.
