Summary
This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Airbus Model A320-111, -211, and -231 series airplanes, that currently requires repetitive inspections for cracking in the transition and pick-up angles in the lower part of the center fuselage area, and corrective action if necessary. That AD also provides for an optional terminating modification for the repetitive inspection requirements. This action would reduce the compliance time for the inspections for cracking of the same area. The actions specified by the proposed AD are intended to detect and correct fatigue cracking in the transition and pick-up angles of the lower part of the center fuselage, which could result in reduced structural integrity of the wing-fuselage support and fuselage pressure vessel. This action is intended to address the identified unsafe condition.
