NW7E7, the A300 only has rudder problems in as much that a pilot can, in extreme situations, break the rudder by inputting full left and right pedal sequentially. However, most planes can be broken if the pilot does stuff that pushes the plane beyond design limits.
Before I get bashed for the AA
A300, the training of those pilots and their awareness of the limitations of the airframe was lacking in certain areas. Whether this was the fault of Airbus or AA
or the FAA has been a matter of much debate on this forum and I really don't want to get into it.
Finally, if you feel unsafe about the 737, what about the MD
-80? It's horizontal stabilizer trim mechanism is a single point of failure. Ouch... And yet it still gets there safely every day.
