I've tried to recreate the incident in the NGX and I had to hold the (springloaded) rudder trim knob to the left for quite some time before anything happend. The behavior from the incident only occured when the rudder trim was almost at the max setting: left roll followed by a partially inverted dive. Of course there might be a difference in behavior between the NGX and the real one, despite all realism. ;)

Not really surprising. You would have to know the speed they were doing, the atmospheric conditions, altitude, attitude, weight, balance, their flap/slat setting at the time, and a few other bits of info in order to try to replicate the incident. How far the rudder can deflect is affected by several things too, for example, the yaw damper movement, which itself has different deflection limits at various speeds. There is also the fact that the PMDG 737 is designed to simulate normal operations, and isn't really an ''accident replicator''. I suspect even a full-motion professional 737 simulator might have some difficulty replicating the incident without all the pertinent info. Al

Well it is all on the tapes so they should easily be able to replicate what happened.
