NTSB narrative

THE UK CERTIFIED PRIVATE PLT WAS FLYING A CROSS COUNTRY FLIGHT WITH HIS UK PRIVATE RATED PASSENGER. ON FINAL APPROACH TO RWY 23, THE PLT ADDED POWER TO ADJUST HIS RATE OF DESCENT. HE ADDED FULL POWER TO NO AVAIL, AND THE RATE OF DESCENT WAS STILL TOO RAPID. THE PLT SAID HE PREPARED FOR AN OFF AIRPORT LANDING. THE PLANE UNDERSHOT THE RWY AND IMPACTED WITH SNOW COVERED TERRAIN, 300 FT SHORT OF RWY 23. THE NOSE GEAR COLLAPSED AND THE WINGS WERE BENT, THE PLANE CAME TO REST 150 FT SHORT OF THE RWY.

Probable cause

THE FAILURE OF THE PILOT TO MAINTAIN THE PROPER DESCENT RATE ON FINAL APPROACH WHICH RESULTED IN A LANDING SHORT OF THE RUNWAY.

  • 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: af8fe8ab7c8c8e48bc9f378a450588aa70fb60178937cf79c264a93b270edc9c; retrieved 2026-09-23T07:50:44.831Z.
