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

NTSB narrative
The pilot stated that he was using 20-degrees of flaps for takeoff, which is not the normal takeoff configuration, because he was testing a new takeoff technique he had seen in an aviation publication. The piloted stated that the aircraft became airborne, sooner than expected, and drifted to the right of the runway centerline. While the aircraft was drifting across the runway it impacted the ground approximately 30' from the runway centerline. In a telephone conversation with the pilot, he stated that the accident could of been avoided if he had built up additional airspeed before liftoff and after liftoff kept the aircraft low in ground effect.
Probable cause
the initial climb airspeed not obtained/maintained after liftoff by the pilot in command. A factor was the improper compensation for wind conditions by the pilot in command.

- 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.
