Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-200 and -300 series airplanes. This proposed AD was prompted by reports that cracks were found on an adjacent hole of certain frames of the center wing box (CWB). This proposed AD would require removing fasteners, a rototest inspection of fastener holes, installing new fasteners; and if necessary, oversizing the holes and doing rototest inspections for cracks, and repairing any cracking that is found. We are proposing this AD to detect and correct cracking on certain holes of certain frames of the CWB, which could affect the structural integrity of the airplane.
