- 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 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
- 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 › Flight into known adverse weather, intentional
- Pilot in command › In-flight planning/decision, poor

NTSB narrative
THE NONINSTRUMENT RATED PLT CALLED FLT SERVICE A DAY BEFORE THE ACCIDENT AND REQUESTED AND RECEIVED AN IFR BRIEFING FOR THE ACCIDENT FLIGHT. THE WX BRIEFER PROVIDED THE PLT WITH THE BRIEFING WHICH CONSISTED OF IFR CONDITIONS AT THE DESTINATION AIRPORT AREA WHICH INCLUDED THE ACCIDENT SITE. GND WITNESSES OBSERVED THE AIRPLANE MANEUVERING IN THE ACCIDENT AREA BEFORE IT ENTERED INTO THE 500 FT CEILING STRATUS CLOUDS. THE PREVAILING VISIBILITY WAS LESS THAN 1 MILE. THE ENGINE SOUND INCREASED RAPIDLY WHEN THE AIRPLANE ENTERED THE CLOUDS ABT 2 SECONDS BEFORE IT COLLIDED WITH THE SIDE OF THE HILL. THE ACFT EXAMINATION DISCLOSED THAT IT STRUCK THE HILLSIDE IN A LEVEL FLT ATTITUDE; THE PROPELLER BLADES AND HUB ASSY SHOWED DAMAGE CHARACTERISTICS CONSISTENT WITH HIGH POWER BEING DEVELOPED AT IMPACT. NO PREEXISTING MALFUNCTIONS AND/OR FAILURES WERE NOTED.
Probable cause
THE PILOT USED POOR JUDGEMENT BY ATTEMPTING A V.F.R. FLIGHT TO AN AREA WITH FORECASTED INSTRUMENT METEOROLOGICAL CONDITIONS AND CONTINUING THE FLIGHT WHEN I.F.R. CONDITIONS WERE ENCOUNTERED.

- 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.
