NTSB narrative
THE PILOT REPORTED THAT UPON ARRIVAL AT THE AIRPORT, HE NOTED THAT THE RUNWAY HAD NOT BEEN RECENTLY PLOWED OF SNOW. A LOW PASS TO THE NORTH OVER THE RUNWAY WAS MADE TO TRY TO DETERMINE THE DEPTH OF THE SNOW. THE PILOT TURNED THE AIRPLANE AROUND AND APPROACHED THE RUNWAY TO THE SOUTH TO MAKE A RUN ON THE RUNWAY AND 'DRAG' THE WHEELS ON THE SNOW. THE WHEELS CONTACTED THE SNOW JUST PAST MID FIELD AND THE PILOT STATED 'IMMEDIATELY WE WERE IN TOO DEEP AND I WAS UNABLE TO PULL IT OUT OR ADD POWER...' THE AIRPLANE NOSED OVER AND CAME TO REST INVERTED. AIRPORT PERSONNEL REPORTED THAT THE AIRPORT WAS NOTAMED CLOSED SINCE DECEMBER 27, 1992. THE PILOT DID NOT MAKE CONTACT WITH THE AIRPORT OPERATOR PRIOR TO THE ACCIDENT AND THE PILOT STATED THAT HE WAS UNAWARE THAT THE AIRPORT WAS CLOSED.
Probable cause
THE PILOT'S FAILURE TO MAINTAIN PROPER ALTITUDE DURING THE LOW PASS. THE SNOW COVERED TERRAIN AND THE PILOT'S INADEQUATE PREFLIGHT PREPARATION WERE FACTORS.

Source notes (4)
- 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.
