- 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

- 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 on ground/water
- 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
- 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 PILOT WAS PERFORMING HIGH-SPEED TAXI TESTS ON THE RUNWAY. THERE WAS NO INTENT FOR FLIGHT. THE EXPERIMENTAL AIRPLANE WAS NEWLY BUILT, AND HAD NEVER BEEN FLOWN. THE PILOT HAD NO EXPERIENCE IN THIS MODEL. WHILE TAXIING DOWN THE RUNWAY WITH THE ENGINE RPM SET AT 2,600, THE LEFT WING BECAME AIRBORNE. THE PILOT TRIED TO RIGHT THE AIRPLANE, HOWEVER IT DRIFTED TO THE RIGHT AND OFF OF THE RUNWAY SURFACE. THE AIRPLANE THEN BECAME AIRBORNE, AND THE PILOT ADDED FULL THROTTLE. THE AIRCRAFT WOULD NOT CLIMB, AND THE ENGINE RPM WOULD NOT INCREASE, SO THE PILOT ELECTED TO LAND IN AN ADJACENT FIELD. THE AIRPLANE COLLIDED WITH TERRAIN DURING THE FORCED LANDING.
Probable cause
THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRPLANE ON THE RUNWAY, AND THE INADVERTENT ROTATION OF THE AIRPLANE, RESULTING IN AN UNPLANNED FLIGHT.

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: 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.
