The FO flying in AA587 had come to American "from another Line", recently..... The Union claimed that "in his former experience", he had been trained to cycle the Rudder pedals as response to a now forgotten abnormal. Airbus reacted to the A300 losing the VS/Rudder pair by "reinforcing the clevis tab retainers to resist calculated load at failure in 587". I also believe they reengineered the Rudder hinges to fail prior to producing this load in the VS.
Made sense, a rudderless a/c can fly without rudder, not without Vertical Stabiliser...
