AA587 wasn't a dutch roll. It started with wake turbulence and ended up with rudder movement causing the VS to fail. The question is was it pilot induced or did the airplane do it. I believe the airplane did it. Our MIA incident at their speed if repeated could be why it happened. I think the FDR actually measures the rudder movement, not pedal movement so would like to see the read out of the MIA incident vs JFK crash and compare them. MIA, the pilots couldn't move the rudder pedals but JFK it shows full deflection. Did anybody ever bother to compare them? Probably not. If I was in the NTSB I would because the FO is being blamed for what the rudders did but I don't think he pushed the rudders, the A300 systems did again. I could be wrong but I don't think so.
