Thats why I specifically said with potential pilot error (I was going to say mechanical failure, but that is highly less likely given the age of the aircraft.)

>"Right, it was that bolded "400'" climb that clearly is what hes pointing at - as the ice caused the drop, then the pilot sharply climbed, then ice-stall, causes plane to yaw pilot corrects the wrong direction causing spin - all in the course of what seems like ~30 seconds?"

Is what my thoughts are.
