AND PROVIDED THE BUILDER OF THE PLANE WARNS THE PILOTS PRIOR TO FLIGHT OF ANY PROBLEMS LIKE THE AIRBUS 300/310.
Interesting point! Even more interesting after you read page 156 of
NTSB report, which says:
To elevate the characteristics of A300-600 rudder system in hiearchy of contributing factors ignores the fact that this system had not been an issue in some 16 million hours of testing and operator experience - until the AAMP trained pilot flew it.
It wasn't rudder deflection alone that tore off the fin, it required help from large sideslip, created by previous rudder cycle. Granted, if pedal forces were heavier, F/O wouldn't be able to make rapid rudder reversals that led to accident. Hard rudder kicks below Va are not bound to hurt your airplane, as long as they're not alternating.
Personally, I think the greatest fault lies with folks who devised such unrealistic scenario for AAMP as overbank with roll control disabled. Chances are that F/O reacted as he was trained on the sim, found out that there really was no need for so much rudder, corrected excessively, kicked again in direction of first input... we know the rest.
BTW ercoupe does have rudders, it's just that their actuation is somewhat unorthodox.
