Summary
This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Airbus Model A319 and A320-200 series airplanes, that currently requires repetitive inspections to detect loose, missing, or discrepant rivets in specified areas of the door frames of the overwing emergency exits, and corrective action if necessary. That AD also requires measurement of the grip length of all rivets in the specified areas, and corrective action if necessary, which terminates the repetitive inspections. This new action would add an inspection for correct dimensions of the interior countersinks of the rivet holes, and related corrective action. The actions specified by the proposed AD are intended to prevent loose, missing, or discrepant rivets, which could lead to reduced structural integrity of the door frames of the overwing emergency exits. This action is intended to address the identified unsafe condition.
