The failure of the aircraft, when the inboard portions of the wing were stalled, to respond to the application of full power in the manner reasonably to be expected in the light of the aeronatical knowledge then available.
Contributing factors:
1. Accumulation of ice on the wings and other surfaces of the airplane, increasing the stalling speed and the drag of the airplane on the power required to maintain flight.
2. Failure of the captain, due to his having lost confidence in the airspeed meters, to realize his close approach to a stalled condition.
3. Action of the captain in descending to attempt a landing at Fargo with known icing conditions and critical ceiling conditions, instead of proceeding to an available alternative.
4. Failure of the dispatcher to recognize the seriousness of weather conditions in the vicinity of Fargo and to direct the pilot to proceed to his alternate.
