Narrative:The commercial certificated pilot was departing on a VFR scheduled commuter flight. The runway was 3,200 feet long and 60 feet wide, and the surface had areas of packed snow and ice. A right crosswind was estimated between 15 to 25 knots. About 300 feet after beginning the takeoff roll, between 30 to 50 knots airspeed, the airplane began to drift to the left, which the pilot was unable to correct. The airplane departed off the left side of the runway and nosed over. The airplane received damage to the wings, fuselage, and empennage. The maximum demonstrated crosswind velocity, takeoff or landing, is 20 knots.
Probable Cause:
Probable Cause and Findings:
The pilot's inadequate planning and decision to initiate a takeoff into a crosswind that exceeded the airplane's demonstrated crosswind component, which resulted in a loss of directional control during the takeoff roll, and subsequent collision with terrain and nose over.
Factors contributing to the accident were the crosswind, an icy runway, and the pilot's failure to abort the takeoff.
