## Summary

We propose to supersede Airworthiness Directive (AD) 96-18-06 for certain Airbus Model A320-211 and -231 airplanes. AD 96-18-06 currently requires visual inspections to detect cracks of the pressurized floor fittings at frame (FR) 36, and renewal of the zone protective finish or replacement of fittings with new fittings if necessary. Since we issued AD 96-18-06, an extended service goal analysis by the manufacturer revealed that the compliance times and repetitive inspection intervals should be reduced to meet the design service goal. This proposed AD would retain the requirements of AD 96- 18-06, with reduced compliance times and repetitive inspection intervals. This proposed AD would also add Model A320-212 airplanes to the applicability. We are proposing this AD to detect and correct fatigue cracking in the pressurized floor fittings at FR 36, which could result in failure of a floor fitting and subsequent depressurization of the fuselage.
