Summary
We propose to supersede Airworthiness Directive (AD) 2017-22- 07, which applies to certain Airbus Model A319 series airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321- 111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2017- 22-07 requires repetitive inspections of the frame forks, and corrective actions if necessary. AD 2017-22-07 also includes optional modifications that constitute terminating action. Since we issued AD 2017-22-07, an evaluation was done by the design approval holder (DAH) indicating that the frame forks and outer skin on the forward and aft cargo compartment doors are subject to widespread fatigue damage (WFD), and a determination was made that a modification of the frame forks must be accomplished. This proposed AD would require modifying certain forward and aft cargo compartment doors, and related investigative and corrective actions. We are proposing this AD to address the unsafe condition on these products.
