Airworthiness Directives; Airbus Airplanes

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200 series airplanes, Model A330-200 Freighter series airplanes, and Model A330-300 series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that certain fuselage structures are subject to widespread fatigue damage (WFD). This proposed AD would require reinforcement modifications of various structural parts of the fuselage, and related investigative and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
