Accident Summary
A single-engine aircraft experienced a runway excursion after landing at an unspecified airport. The pilot had circled the runway twice to assess wind direction and runway conditions before attempting the landing. The runway appeared clear to the pilot, with a few ice patches on the surface and snow mounds off to the sides.
Sequence of Events
Upon touchdown, the left landing gear assembly encountered a patch of snow described as "low flat." The aircraft then began to pull to the left. Despite the pilot's efforts, the airplane continued off the side of the runway and came to rest upright in a snow-covered field. The event occurred during daylight hours under conditions of snow-covered terrain.
Findings
No determination of probable cause was provided in the source material. The runway surface contained ice patches and snow mounds, and the presence of a snow patch on the runway was identified as the immediate trigger for the loss of directional control. The aircraft sustained no further damage beyond the excursion itself.
