The actions at Airbus were absoultely disgusting. Why were they warning AA pilots not to make strenuous rudder movements? Perhaps because they knew of the possible consequences?? It's probably because the cost involved in design changes would slow them down in their race with Boeing. In an emergency, a pilot is likely to do whatever he (she) can to correct the situation. Airbus should've designed the tail structure better so that sudden rudder movements in emergency situations would not overstress it. Chris No fan of Airbus! "Airbus understood that losing a tail fin would prove catastrophic. Even so, they kept their concerns to themselves until after a tail fin did break off one of its jets, causing the second-worst aviation disaster in U.S. history."
