- 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 was destroyed during an in-flight collision with the terrain and subsequent explosion/post-impact fire. A witness to the accident reported the airplane started the takeoff roll at the beginning of runway 09 and appeared to be accelerating slower than normal. The witness reported, "The takeoff roll looked normal ... but the aircraft seem to roll out longer than normal for this type of aircraft ... this aircraft seemed to roll about 3,500 feet before rotation. After rotation the aircraft pitched up and down several cycles then settled down. But after the pitch cycles stopped the plane was not climbing. The landing gear was not cycled up it remained down. The plane was about 200 feet altitude when the up, down pitching began again. I noted the plane climbed about another 50 ft. Then the plane rolled to the left and entered a vertical position and impacted the ground about 1,000 ft. north of the runway centerline. Aircraft exploded on impact." The pilot had logged two flights in the accident airplane, accumulating 1.2 hours. Excluding the two previous flights in the accident airplane, the pilot did not have any other flight time in the same model as the accident airplane. No anomalies were found that could be associated with a pre-impact condition.
Probable cause
The pilot not maintaining aircraft control during the initial climb after takeoff and the inadvertent stall/spin. A factor to the accident was the pilot's total lack of experience in accident airplane.

- 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.
