NTSB narrative
DURING THE IFR APPROACH TO THE AIRPORT, THE FLIGHT HAD BEEN CLEARED FOR THE ILS/DME FOR RUNWAY 8. THE PILOT PERFORMED THE PUBLISHED PROCEDURE TURN AND WAS ESTABLISHED ON THE LOCALIZER AND GLIDE SLOPE AT ABOUT 5.5 MILES DME. THE FLIGHT CONTINUED THE DESCENT AS THE PILOT COMPLETED THE BEFORE LANDING CHECKLIST. AT ABOUT 5 MILES DME, THE PILOT ATTEMPTED TO CALL THE FSS TO REPORT FINAL APPROACH FIX INBOUND, HOWEVER, HE HAD TO WAIT FOR ANOTHER AIRPLANE TRANSMITTING. THE PILOT THEN CONTACTED THE FSS AND REPORTED 4.5 MILES DME. SHORTLY AFTER THE RADIO CALL, THE PILOT FELT THE AIRPLANE CONTACT THE GROUND. THE PILOT REPORTED THAT HIS LAST INSTRUMENT SCAN THAT HE COULD REMEMBER SHOWED THAT HE WAS ON THE GLIDE PATH AND LOCALIZER AT AN ALTITUDE OF 1,250 FEET. AFTER THE ACCIDENT, THE PILOT REPORTED THAT THE VISIBILITY WAS ABOUT 100 YARDS AND BLOWING SNOW.
Probable cause
PILOT FACTOR IN THAT THE PROPER GLIDEPATH AND ALTITUDE WAS NOT MAINTAINED. FACTORS TO THE ACCIDENT WERE: INATTENTIVENESS AND SNOW.

- 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.
