Airworthiness Directives; Airbus SAS Airplanes

We propose to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-223F and Model A330-243F airplanes. This proposed AD was prompted by a report of cracking at fastener holes located at a certain frame on the lower shell panel junction. This proposed AD would require repetitive special detailed inspections (rototest) of certain fastener holes located at the lower shell junction of a certain frame on both left-hand (LH) and right-hand (RH) sides, and applicable related investigative and corrective actions. We are proposing this AD to address the unsafe condition on these products.
