- 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
- Initial climb
- 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
- Stall/spin
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The airplane rolled right and collided with terrain during the initial climb after takeoff. A surviving passenger said that the takeoff and initial climb rate seemed normal. The passenger reported that about 1 1/2 to 2 minutes into the flight, the airplane, unexpectedly and without warning, went hard right and pitched straight down into the ground. Ground witnesses said that the airplane was 150 to 200 feet above the ground, and did not appear to gain any additional altitude. One witness, on an access road just north of the airport, had a profile view of the airplane during the majority of the accident sequence. He reported an "excessive" angle of attack on the takeoff. He saw the nose pitch down, and thought the airplane was about 100 feet above the ground. The witness then saw the nose pitch up again, increasing the angle of attack. The pitch attitude was steep; the witness said he was able to see the tops of the wings. He stated that the airplane flew straight ahead under controlled conditions, but appeared to be "mushing" through the air. He lost sight of the airplane as he rounded a bend in the road. When he saw the airplane again it was in a left descending spiral. Investigators found no anomalies that would have precluded normal operation of the airframe or engine.
Probable cause
the pilot's failure to maintain an adequate airspeed resulting in a stall/spin.

- 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, coordinates. 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.
