Accident Summary
During a landing on a runway contaminated with patches of snow and ice, the pilot lost control of the airplane. The aircraft touched down near the centerline with all three wheels on the runway surface before it began to veer left. Despite applying right rudder, the airplane continued to the left, with the pilot noting it behaved "as [if] on ice even though none was visible."
Pilot Actions
The pilot added power in an attempt to regain directional control, but the left main landing gear subsequently caught a snow bank on the left edge of the runway. The airplane then went over the snow bank and nosed over. The pilot reported no mechanical malfunctions or failures.
Pilot and Environmental Details
The pilot had accumulated 286 hours of total flight time, with 107 hours in the accident make and model. The runway was 4,902 feet long and 75 feet wide. Area winds were from approximately 40 degrees left of the runway heading at 3 knots.
