Narrative:
The airplane arrived at Montrose around 09:00 and dropped off one passenger. The airplane remained parked for approximately 50 minutes until the crew received their IFR clearance at 09:55. The airplane taxied out to runway 31. After rotation the airplane reportedly yawed to the right. The airplane impacted terrain to the right of runway and slid approximately 1,400 feet, through the airport perimeter fence, across a road and through an adjacent fence. The airplane came to rest within 200 feet of a dairy farm. Weather at the time of the accident was reported as winds calm, visibility 1 1/4 statute miles, light snow and mist, sky condition few 500 feet agl, overcast 900 feet agl, temperature -01 degrees Celsius (C), dewpoint -02 C, altimeter 29.67 inches.

PROBABLE CAUSE: "The National Transportation Safety Board concludes that the probable cause of this accident was the flight crews failure to ensure that the airplanes wings were free of ice or snow contamination that accumulated while the airplane was on the ground, which resulted in an attempted takeoff with upper wing contamination that induced the subsequent stall and collision with the ground. A factor contributing to the accident was the pilots lack of experience flying during winter weather conditions."
