Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-202, -203, -223, -243, -302, -323, -342, and -343 airplanes; and Model A340-313 airplanes. This proposed AD was prompted by reports that a specific batch of cargo doors might have deviations in quality related to door structure, such as irregular bore holes, improper application of sealant and paint, or uncleanliness. This proposed AD would require inspecting to identify the part and serial numbers of the forward and aft cargo doors, and replacing the affected cargo doors. We are proposing this AD to prevent the degraded structural capability of the cargo door, a primary structure, from leading to failure of the door, which could lead to a breach through the door or the door detaching from the airplane, resulting in potential rapid decompression.
