NTSB narrative
THE PLT & A FRIEND FLEW TO ANOTHER ARPT IN THE LOCAL AREA. AFTER ARRIVING AT THAT ARPT, THE PLT CHECKED THE WIND SOCK & ELECTED TO LAND ON RWY 11. DRG THE LANDING, THE ACFT ENCTRD SNOW ON THE RWY THAT WAS DEEPER THAN EXPECTED. DUE TO THE SLOPE OF THE RWY, THE PLT ELECTED TO TAKE OFF IN THE OPPOSITE DIRECTION (DOWNHILL) WITH A SLIGHT TAILWIND. THE ACFT BECAME AIRBORNE, BUT WOULD ONLY CLIMB ABOUT 5 FT. SUBSEQUENTLY, IT HIT A 6 FT SNOW BANK & NOSED OVER. THE PLT STATED THAT HE THOUGHT THE ACDNT OCCURRED DUE TO WIND GUSTS FROM BEHIND & THE ACFT HITTING DRIFTS THAT SLOWED IT DOWN.
Probable cause
THE PILOT SELECTED A RUNWAY WITH UNSUITABLE CONDITIONS FOR TAKING OFF. THE UNFAVORABLE WIND AND TERRAIN CONDITIONS WERE RELATED FACTORS.

- 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.
