- 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
- Defining eventThe 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
- Aerodynamic 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
A witness reported that the pilot departed from the grass airstrip in the weight-shift controlled aircraft about three minutes prior to the accident. He reported that the aircraft was about 100 - 150 feet above ground level. He stated, “The plane seemed to go up and then the left wing dipped, and then the airplane spiraled to the ground.” He reported that the engine was running. The impact damage to the aircraft was consistent with a steep, nose down attitude. The inspection of the aircraft’s weight-shift control system revealed no preexisting anomalies. The inspection of the aircraft logbook indicated that the last conditional maintenance inspection was conducted on December 15, 2006. A review of the aircraft experimental operating limitations as of August 28, 2005, item #18, stated that, “No person shall operate this aircraft unless the preceding twelve calendar months it has had a conditional inspection performed, and recorded in the aircraft maintenance records.”
Probable cause
The pilot's failure to maintain adequate airspeed resulting in an aerodynamic stall.

Source notes (4)
- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2009-07-15.
