- 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
- Landing
- 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
The pilot reported that while on short final about 20 feet above the ground, he noticed the "attitude was a little flat." He reported that the airplane lost altitude "so fast, he didn't have time to react or even think to put the nose down or add power". The airplane impacted terrain, which resulted in substantial damage to the left wing.
The pilot reported that his conclusion as to why the accident occurred was that the airplane "flat" stalled about 15 to 20 feet above the ground because he was "so focused on hitting the front of the runway" and didn't keep the airspeed "up."
The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot's failure to maintain pitch attitude, which resulted in the airplane exceeding its critical angle of attack and a subsequent aerodynamic 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. 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.
