## Summary

We propose to supersede Airworthiness Directive (AD) 90-11-05 for certain Airbus Model A300 series airplanes and Model A300 B4-600 series airplanes. AD 90-11-05 currently requires repetitive detailed inspections for cracking in the aft hinge brackets of the outer shroud box that is located in the outer wing box, and related investigative and corrective actions if necessary. Since we issued AD 90-11-05, we have determined that a change to certain compliance times is needed. This proposed AD would continue to require doing repetitive detailed inspections for cracking in the hinge brackets of the forward and aft outer shroud boxes that are located in the outer wing box, and related investigative and corrective actions if necessary; and would add airplanes to the applicability. We are proposing this AD to detect and correct cracking of the aft hinge brackets of the outer shroud box; such cracking could affect the structural integrity of the airplane.
