- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
- Part 91: General Aviation
- Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
- Maneuvering
- 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 collision with terrain/water
- 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
- Visual flight rules (VFR) flight into instrument meteorological conditions (IMC)
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
- Destroyed
Cause areas
- Pilot in command › In-flight planning/decision, inadequate
- Pilot in command › VFR flight into imc, continued
- Pilot in command › Weather evaluation, inadequate

NTSB narrative
THE CERTIFICATED NON-INSTRUMENT RATED COMMERCIAL PILOT AND THREE PASSENGERS DEPARTED ON A RETURN PORTION OF A CROSS COUNTRY FLIGHT OVER HIGH MOUNTAINOUS TERRAIN. THE PILOT OBTAINED A WEATHER BRIEFING FOR THE FIRST PORTION OF THE FLIGHT, BUT NOT FOR THE RETURN FLIGHT. A WITNESS REPORTED THAT THE MOUNTAIN TOPS IN THE AREA OF THE ACCIDENT WERE OBSCURED BY CLOUDS. WHILE IN A LEFT TURN, THE AIRPLANE STRUCK SNOW COVERED TERRAIN AT THE END OF A BOWL SHAPED CANYON, ABOUT 400 FEET BELOW THE TOP OF A RIDGE LINE. NO MECHANICAL MALFUNCTIONS WERE FOUND WITH THE AIRPLANE.
Probable cause
The pilot's inadequate weather evaluation; inadequate in-flight planning and decision making; and the pilot's continued VFR flight into instrument meteorological conditions.

- 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.
