Incident Details
A dual student was at the controls of the aircraft during the landing approach, flare, and touchdown, according to the pilot-in-command's written statement. The flight instructor reported that upon touchdown at normal speed on the ice-patched 50-foot-wide runway, the aircraft drifted right of the centerline. The instructor noted a contribution from a left crosswind.
Pilot Statements
The flight instructor stated that he was unable to correct the drift using aileron, rudder, and brakes. The aircraft subsequently slid into a three-foot-high snow bank along the edge of the runway.
Post-Accident Inspection
During the post-accident investigation, a functional test of the brake system revealed no anomalies.
