Airworthiness Directives; Airbus Airplanes

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series 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 inspections of certain fastener holes, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct cracking on the lower shell panel junction; such cracking could lead to reduced structural integrity of the fuselage.
