NTSB narrative
JUST AFTER TOUCHDOWN ON THE PLOWED HALF OF THE RUNWAY THE RIGHT SKI CONTACTED THE EDGE OF THE SNOW BERM, CAUSING THE AIRPLANE TO GROUND LOOP. THE PILOT STATED THAT IN RETROSPECT SHE SHOULD HAVE LANDED ON THE UNPLOWED HALF OF THE RUNWAY.
Probable cause
THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRPLANE. CONTRIBUTING TO THE ACCIDENT WERE THE SNOW BERM AND THE PILOT'S LACK OF TOTAL EXPERIENCE IN THE TYPE OF OPERATION (SKI EQUIPPED AIRPLANES).

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1992-04-08.
