Notice of proposed rulemaking (NPRM).

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A300 series airplanes, and Airbus SAS 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). This proposed AD was prompted by reports of cracking at a certain hole location on the left-hand (LH) side of a certain frame (FR). This proposed AD would require repetitive inspections for discrepancies of certain areas in and around the fuselage, as specified in two European Union Aviation Safety Agency (EASA) ADs, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
