There were heavy snow showers in progress at the time of the accident and the runway was covered by snow.

The NTSB determined the probable cause to be: Loss of directional control by the pilot, during take-off ground run. Contributing to this accident were a loss of power on the left engine due to snow ingestion, heavy snow showers in progress and an icy, snow covered runway
