NTSB narrative

The pilot reported that it was snowing during his preflight activities and takeoff roll. A snowplow operator stated that he had cleared approximately four passes on either side of the runway centerline when the accident airplane taxied onto the runway. The pilot back-taxied on the departure runway to determine how much snow covered the runway. During the subsequent takeoff roll, at approximately 80 knots, the left main landing gear encountered some deeper snow that caused the airplane to swerve left off of the runway centerline. The pilot attempted to correct the left swerve with right rudder input, but the airplane continued off the left side of the runway. The airplane was substantially damaged when its nose landing gear impacted a snowbank.

Probable cause

The pilot's failure to maintain directional control during the takeoff roll. Contributing to the accident was the snow on the runway and the snowbank.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
