A proposal is not in force. If adopted, it becomes an AD, usually with changes. Only the Federal Register edition is official.

Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-841 and Model A330-941 airplanes. This proposed AD was prompted by reports of crack findings on the sloping rib. This proposed AD would require a repetitive inspection of the external surface of each sloping rib and each slat 1 inboard seal, and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
