Actually, the Colgan stall was not caused by icing, the aircraft was in icing conditions and the Increase REF switch was selected and forgotten about. Distraction caused the flight crew to allow the speed to reduce to the stick shaker onset, at this stage the aircraft was approx 20 knots above an actual stall. The aircraft only entered an actual stall when the Captain mishandled the recovery and on application of full power pulled hard back inducing an aerodynamic stall, to further compound the problem the FO announced that she was raising the gear and proceeded to retract the flaps. So this incident is very similar to the initial stages of the above occurrences, the only difference in the outcome was due to the crew not mishandling the recovery. That is where the training / experience and fatigue argument come into it!!
