NTSB narrative

THE AIRPLANE TOUCHED DOWN ABOUT 30 FEET SHORT OF THE APPROACH END OF THE RUNWAY IN ABOUT 2 FEET OF SNOW, THEN NOSED OVER ONTO THE RUNWAY. THE PILOT STATED THAT HE THOUGHT THE FLAT LIGHTING CONDITIONS CONTRIBUTED TO HIS FINAL APPROACH ALTITUDE BEING TOO LOW. THE PRIVATE PILOT REPORTED HAVING A TOTAL OF 430 FLIGHT HOURS, OF WHICH ONLY 1.5 WAS AT NIGHT AS THE PIC. THE ACCIDENT OCCURRED ABOUT 50 MINUTES AFTER SUNSET.

Probable cause

THE PILOT FAILED TO MAINTAIN PROPER ALTITUDE DURING THE FINAL APPROACH. CONTRIBUTING TO THE ACCIDENT WAS THE PILOT'S LACK OF TOTAL EXPERIENCE PERFORMING LANDINGS IN REDUCED LIGHT CONDITIONS, THE POOR LIGHT CONDITION AT DUSK, AND THE SNOW COVERED TERRAIN.

  • 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.
  • API snapshot SHA-256: e2812f4072afd9a5957634abc3062cec51916beccf1a398bef231e5c79711a0f; retrieved 2026-09-23T03:28:25.425Z.
