Abstract
We are superseding Airworthiness Directive (AD) 90-11-05 for certain Airbus Model A300 B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4- 203 airplanes and Model A300 B4-600 series airplanes. AD 90-11-05 required 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. This new AD changes certain compliance times and adds airplanes to the applicability. This AD was prompted by reports of cracks in the aft hinge brackets of the outer shroud box that is located in the outer wing box, which were found during routine maintenance checks, and our subsequent determination that a change in inspection compliance times is needed. We are issuing 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.
