it hasn't been proven to my satisfaction.
I've moved the rudder on the 9...it has a limiter and I couldn't shake it apart.
put a limiter on the a300 and you might have something
there was a dissenting view from one member of the NTSB

Off topic but, since you've raised this one, it needs to be looked at: I'd be very surprised if the A300-600 hasn't got a rudder travel limiter. The A310 had one from service entry in 1983, and the A300-600 is of similar vintage (1984?). If memory serves, the A310 has a comparable (composite) fin and rudder to the A300-600. The A310-200 limiter "reduces the pedals and rudder deflection from ± 30° at speed below 165kt to ± 5° at 310kt and above." [FCOM, 1985]
Am neither engineer nor test pilot, but what Nocti says makes sense. Presumably, the speed threshold on both types would have been reviewed after the A300-600 accident.
