- 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
- Loss of control in flight
- 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
- Substantial
Cause areas
- Pilot in command › Aircraft control, not maintained
- Pilot in command › Spatial disorientation

NTSB narrative
THE AIRPLANE CRASHED AT THE 1,500 FOOT LEVEL OF A MOUNTAIN LOCATED APPROXIMATELY 12 MILES NORTHWEST OF MCGRATH, ALASKA. OTHER PILOTS IN THE AREA STATED THE WEATHER WAS 1,000 FOOT OVERCAST, WITH 1.5 MILES VISIBILITY IN FOG AND SMOKE. THEY ALSO STATED THAT THE MOUNTAIN TOPS WERE OBSCURED. THE RIDGE WHICH THE AIRPLANE CROSSED WAS THE LAST RIDGE BETWEEN OPHIR, THE DEPARTURE POINT, AND MCGRATH, THE DESTINATION.
Probable cause
THE PILOT'S LOSS OF CONTROL IN FLIGHT DUE TO SPATIAL DISORIENTATION WHILE ATTEMPTING TO OPERATE UNDER VISUAL FLIGHT RULES WHILE IN INSTRUMENT METEOROLOGICAL CONDITIONS. CONTRIBUTING TO THE ACCIDENT WAS THE MOUNTAINOUS 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.
