Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 series airplanes; Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Model A310 series airplanes. This proposed AD was prompted by a report indicating that during inspections to detect corrosion of the bulk cargo doors, several cracks were discovered. This proposed AD would require a general visual inspection of the bulk cargo door frame to identify any structural repairs, a detailed visual inspection of the frame at the repaired area for any cracking if necessary, and corrective actions if necessary. We are proposing this AD to detect and correct cracking of the bulk cargo doors; such cracking could result in rapid airplane decompression or possible loss of the bulk cargo door.
