On November 28, 2004, at 0955 mountain standard time, a Canadair Ltd, CL-601-2A12, N873G, owned by Hop a Jet, Inc., and operated by Air Castle, was destroyed when it impacted terrain during the take off roll from Montrose Regional Airport (MTJ), Montrose, Colorado. A postimpact fire ensued. Instrument meteorological conditions prevailed at the time of the accident. The non-scheduled domestic passenger flight was being operated on an instrument flight rules flight plan under the provisions of Title 14 CFR Part 135. The captain, flight attendant and one passenger were fatally injured. The first officer, and two passengers sustained serious injuries. The flight was departing at the time of the accident and was en route to South Bend, Indiana.
Airport personnel reported that the airplane arrived around 0900 and dropped off one passenger. The airplane remained parked at the fixed base operator for approximately 50 minutes. The FAA stated that the pilot contacted Denver Air Traffic Control to receive his instrument flight rules clearance at 0955. According to a witness at the airport, the airplane taxied out to runway 31, taxied onto the runway and performed a static run-up of a duration of approximately 1 minute. The initial ground roll appeared to be uneventful and then the witness lost sight of the airplane due to the snow and low visibility. Several other witnesses, located towards the departure end of the runway, reported hearing a loud "boom" or "whooshing." The airplane was observed by one witness to yaw to the right, putting the tail of the airplane perpendicular to the runway. 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.
Parties to this investigation include the Federal Aviation Administration, Air Castle Worldwide Executive Jet Charter, General Electric, Bombardier, and Montrose County. Accredited representatives include the Canadian Transportation Safety Board with technical liaison support from Transport Canada.

It certainly looks like there were ideal conditions for frost to form on the wing.
Also our Ops dept. said they had heard reports of poor braking action (MU's in the 20's) at Montrose that morning.
