It's whatever version of the A300-600 AA has. I think the major difference between the AA version and the standard version is the ability to polish the aluminum rather than paint it.

The AD [airworthiness directive] was prompted by French aviation authorities which had reported similar problems in two Airbus A-300s which had suffered tail corrosion that could result in failures. The FAA warned that "since an unsafe condition has been identified that is likely to exist or develop on other airplanes of the same type design . . . this AD is being issued to prevent failure of both spring boxes of the variable lever arm due to corrosion damage, which could result in jammed rudder pedals, loss of rudder control, and consequent reduced controllability of the airplane."
