Airworthiness Directives; Airbus Airplanes

We propose to supersede Airworthiness Directive (AD) 98-18-24, which applies to certain Airbus Model A320 series airplanes. AD 98-18- 24 requires repetitive inspections to detect cracking in the inner flange of a certain door frame, and corrective actions, if necessary. AD 98-18-24 also provides an optional terminating action for the repetitive inspections. Since we issued AD 98-18-24, it has been determined that the compliance times for the repetitive inspections must be reduced. This proposed AD would continue to require the repetitive inspections of the inner flange of a certain door frame, with reduced repetitive inspection intervals, and corrective action if necessary. We are proposing this AD to address the unsafe condition on these products.
