Circumstances:
At approximately 0329LT, the airplane crashed on takeoff from Wold-Chamberlain Field, Minneapolis, Minnesota. A number of the 62 persons (including 2 infants) aboard suffered serious injuries but there were no fatalities. Fire, which broke out a short time after all occupants were evacuated, consumed the aircraft. The aircraft took off normally and climbed to a height of about 100 feet. It then gradually nosed over and entered a descent which continued until it struck the ground. Sky conditions were clear; however, the prevailing visibility was about three miles in fog, and in localized areas around the airport it was reduced to lens than a mile by patches of denser fog. Takeoff was made on runway 22 and the climbout was a from a lighted, built-up section toward an open, unlighted area. The Board believes that the pilot while trying to remain contact in reduced visibility allowed the nose of the aircraft to drop when flaps were retracted because of inattention to flight instruments. The darkness and reduced visibility during climbout contributed to a sensory illusion which completely obscured the fact of descent from the pilot.
Probable cause:
The Board determines that the probable cause of this accident was the pilot's inattention to flight instruments during takeoff in conditions of reduced visibility.

Circumstances:
The airplane departed Minneapolis-Wold Chamberlain on a flight to Seattle with several intermediate stops. Approaching Fargo-Hector Field at night, the crew encountered icing conditions. The airplane became unstable and pitched up and down. The captain increased engine power when the airplane stalled and crashed in a prairie located in Moorhead, bursting into flames. The airplane was destroyed by a post crash fire. A pilot survived while 14 other occupants were killed.
Probable cause:
Upon the basis of the foregoing findings and of the entire record available at this time, investigation team found that the probable cause of the accident was the failure of the aircraft, when the inboard portions of the wings were stalled, to respond to the application of full power in the manner reasonably to be expected in the light of the aeronautical knowledge then available.
Contributing factors:
- 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.
- Failure of the captain, due to his having lost confidence in the air-speed mete to realize his close approach to a stalled condition.
- 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 alternate.
- 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.
