Bell 206 L4 helicopter VT-SPA owned and operated by Span Air Pvt. Ltd. New Delhi, was engaged in a charter flight from Mussorie to Deharadoon on 02.01.2001. The helicopter took off at 11:30 hours from Mussoorie under the command of Capt. R K Yadav with five passengers on board.

The helicopter, along with the other helicopter VT-SPB which took off three minutes earlier, followed a northerly heading to show snowfall to the passengers. After about five minutes VT-SPB turned left for Doon Valley, and Capt Yadav made a 180 degree turn, hit a tree and crashed. Five persons including the pilot received fatal injuries and one passenger survived with serious injuries. There was a minor post impact fire.

The probable cause of the accident is attributed to: "Accident was caused when pilot after noticing the wires late, applied rapid cyclic control, resulting in helicopter decelerating, loss in translational lift, increased power demand which was not available. This caused development of vortex ring with blade root stall, recovery from which was not possible. Low flying and overloading were the contributory causes to the accident.

Factor: Pilot - Non Adherence to the approved procedures.
