Airworthiness Directives; Airbus Airplanes

We propose to supersede Airworthiness Directive (AD) 2014-08- 02 for certain Airbus Model A300 B4-600 and A300 B4-600R series airplanes. AD 2014-08-02 requires modifying the profile of stringer run-outs of both wings, including a high frequency eddy current (HFEC) inspection of the fastener holes for defects, and repairs if necessary. Since we issued AD 2014-08-02, further analysis in the context of widespread fatigue damage (WFD) concluded that a shorter compliance time is necessary to meet specified requirements to address WFD. This proposed AD would retain the actions required by AD 2014-08-02 and would revise the compliance times. We are proposing this AD to address the unsafe condition on these products.
