NTSB narrative
THE STUDENT PILOT, WITH 1 HOUR OF SOLO FLIGHT TIME, WAS PERFORMING TOUCH AND GO LANDINGS AT NIGHT ON A SNOW PACKED ICY RUNWAY WHEN THE ENGINE SPUTTERED. THE PILOT LOST CONTROL OF THE AIRPLANE DURING THE ABORTED TAKEOFF AND COLLIDED WITH A SNOWBANK. DISCUSSIONS WITH THE PILOT COULD NOT ASCERTAIN THE POSITION OF THE CARBURETOR HEAT CONTROL DURING THE TAKEOFF ATTEMPT. A POST ACCIDENT EXAMINATION AND RUN UP OF THE ENGINE REVEALED NO ANOMALIES. THERE WAS NO INSTRUCTOR ENDORSEMENT IN THE PILOT'S LOGBOOK AUTHORIZING NIGHT FLIGHT OPERATIONS. THE MANNER IN WHICH SOLO FLIGHT LANDINGS AND TAKEOFFS WERE TO BE PERFORMED WAS NOT STIPULATED BY THE FLIGHT INSTRUCTOR IN THE PILOT'S LOGBOOK.
Probable cause
THE FAILURE OF THE PILOT TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRPLANE DURING THE ABORTED TAKEOFF. CONTRIBUTING TO THE ACCIDENT WERE THE PARTIAL LOSS OF ENGINE POWER FOR UNDETERMINED REASONS, THE ICY RUNWAY CONDITION, AND THE PILOT'S LACK OF TOTAL EXPERIENCE IN THE TYPE OF OPERATION.

- 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. 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.
