To answer your original question - negative. Design loads would have been established and stress would have designed the structure to with stand them with the required margins. It's not unusual for manufacturers to increase those margins slightly when introducing new technologies, like composites say. Though I didn't or read the accidents reports for the New York Airbus fin failure. I would guess they found that the rudder was commanded through side-to-side oscillations setting up a force hysteresis loop which increased the loads. Don't know if they allowed for that in design.
