- First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- In flight encounter with weather
- Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary

NTSB narrative
WHILE EN ROUTE FROM BELOIT, KS, TO STEAMBOAT SPRINGS, CO, THE PLT LANDED AT FORT MORGAN, CO, FOR FUEL. HE TELEPHONED THE DENVER AFSS TO OBTAIN A WX BRIEFING & WAS TOLD VFR FLT WAS NOT RECOMMENDED. ACCORDING TO THE PLT, AS HE APCHD BUFFALO PASS AT 11,500 FT MSL, HE ENCTRD 'A SUDDEN, STRONG DOWNDRAFT' & APPLICATION OF FULL POWER DID NOT ARREST THE SINK RATE. SUBSEQUENTLY, THE AIRPLANE STRUCK TREES AS THE PLT WAS TURNING AROUND. ACCORDING TO THE PASSENGER, IFR CONDITIONS WERE ENCTRD, THE ACFT BEGAN ACCUMULATING ICE & IT CRASHED DRG A TURN TO REVERSE DIRECTION. APRX 28 MI WEST AT HAYDEN (ELEV 6597'), THE 1050 MST WX WAS IN PART: SKY PARTIALLY OBSCD, 1000' SCATTERED, ESTD CEILING 3000' OVC, VIS 6 MI WITH LIGHT SNOW, WIND 250 DEG AT 7 KTS.
Probable cause
CONTINUED VFR FLIGHT BY THE PILOT INTO INSTRUMENT METEOROLOGICAL CONDITIONS (IMC) AND HIS DELAY IN DIVERTING OR REVERSING COURSE. THE TERRAIN, WEATHER CONDITIONS, WING ICE, AND TREES WERE CONSIDERED TO BE CONTRIBUTING 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.
