Airworthiness Directives; Airbus Model A319 and A320 Series Airplanes

This amendment supersedes 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 amendment requires repetitive ultrasonic inspections for fatigue cracking in the wing/fuselage joint cruciform fittings at a reduced inspection threshold and repetitive interval. This amendment also adds airplanes to the applicability. The actions specified by this 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.
