Summary
This document proposes the supersedure of an existing airworthiness directive (AD), applicable to all Airbus Model A320 series airplanes, that currently requires repetitive ultrasonic inspections to detect fatigue cracking in the wing/fuselage joint cruciform fittings, and corrective actions if necessary. This action would require repetitive ultrasonic inspections for fatigue cracking in the wing/fuselage joint cruciform fittings at a reduced inspection threshold and repetitive interval. This action also would add airplanes to the applicability of the existing AD. The actions specified by the proposed AD are intended to detect and correct fatigue cracks on the wing/fuselage joint cruciform fittings, which could result in reduced structural integrity of the wing/fuselage. This action is intended to address the identified unsafe condition.
