Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus transport category airplanes. This proposed AD would require repetitive eddy current inspections for cracks of the stiffener fittings of the fuselage at frame (FR) 12A, and corrective actions if necessary. This proposed AD also provides a terminating action for the inspections. This proposed AD results from reports of cracks on the upper attachment fitting of the stiffener fitting at FR12A. We are proposing this AD to prevent failure of the stiffener fittings, which could result in the reduced structural integrity of the floor and rods around FR12A.
