- Route
- From Williamsburg Jamestown Airport (JGG), Williamsburg, VATo Williamsburg Jamestown Airport (JGG), Williamsburg, VA
- Aircraft age
- About 3 years (built 2011)
- 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
- Maneuvering · low-altitude flying
- 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
- Substantial

NTSB narrative
The pilot stated that he was flying the weight-shift control aircraft over a river while the passenger took photos. As he slowed and descended the aircraft near a bird's nest in order for the passenger to capture a photo, the aircraft entered an aerodynamic stall. The pilot applied full engine power to recover, but the aircraft continued to sink before impacting the river, resulting in substantial damage. The pilot and passenger subsequently egressed and swam to the shore. The pilot stated that there were no mechanical malfunctions or anomalies of the aircraft or engine that would have precluded normal operation of the airplane.
Probable cause
The pilot's failure to maintain airspeed while maneuvering at low altitude, which resulted in an aerodynamic stall and impact with water.

Source notes (5)
- 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 2014-05-25.
- API snapshot SHA-256: 2e6a4d62e300e43d8a1bed42f809ee1c133450c55313835d7987a8b897f02e2e; retrieved 2026-09-15T23:40:32.109Z.
- Corrected after a review of the NTSB narrative and the aircraft's make and model, which establish these values: aircraft category. EVOLUTION TRIKES REVO is a weight-shift (trike); the manufacturer builds nothing else. The NTSB MDB codes it AIR (Airplane), which is how the aircraft was registered rather than what it is.
