- 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
- Destroyed

NTSB narrative
Witnesses observed the airplane takeoff, and level off as it flew down the runway at a low altitude. It then entered a steep nose-up climb, followed by a sudden roll to the right and a steep nose-down descent. Video images from a security camera, showed the airplane descended at about 20° to 30° nose-down attitude until it impacted the terrain. Examination of the wreckage did not find any anomalies that would have contributed to the accident. Signatures on the propeller were consistent with the propeller being driven during the impact sequence. A review of the pilot's video camera found recordings of similar maneuvers that had a right rolling tendency during the airplane's recovery to level flight. The circumstances of the accident were consistent with the pilot's exceedance of the airplane's critical angle of attack during a steep climb resulting in an aerodynamic stall and collision with terrain.
Probable cause
The pilot's exceedance of the airplane's critical angle of attack resulting in an aerodynamic stall and collision with terrain.

- 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 2015-09-25.
