A Beechcraft C99, N216CS, departed the runway during an attempted takeoff at Durango La-Plata County Airport (DRO), Colorado. As the flight crew taxied onto the runway, the pilot flying reported the wind was 40 degrees right of runway heading at 10 knots with no gusts and the runway was slick. On takeoff roll passing 60 kts, the pilot noticed a rising crosswind but was able to maintain centerline. Passing 80 kts the flight crew lost the ability to maintain centerline with full right aileron deflection.
The pilot attempted to rotate and lift off but the airplane went into deep snow on the side of the runway. The pilot then reduced power to idle before going off the runway. The airplane departed the left side of the runway and the nose wheel collapsed. The airplane came to rest about 66 feet off the left side of runway 21 and 2,800 ft from the departure end.
Postaccident examination of the airplane showed aft crushing to the nose radome and skin wrinkling on the underside of the fuselage around the nose landing gear well. Both engines sustained damage beyond repair.

Probable Cause:

Probable Cause: "The pilot's inability to maintain directional control during takeoff in crosswind conditions on a contaminated runway, which resulted in a runway excursion."
