- 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
- Total loss of engine power (non-mechanical)
- 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
- Fuel exhaustion
- 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 stated that the purpose of the flight was to reposition the airplane due to Hurricane Francis. He visually checked the fuel tanks before the flight departed and noted the level in both was within 3 inches from the top. The flight departed, and initially climbed to 1,000 feet mean sea level (msl), then later climbed to 1,500 feet msl. When the flight was near Monticello, Florida, the engine sputtered and he maneuvered the airplane towards a nearby lake. He turned base and final for landing on the lake and with 40 degrees of flaps selected, the airplane cleared tall trees near the lake. After clearing the trees he pushed the yoke forward to descend, which caused the airplane to accelerate. He landed on the water but ran out of room and the left wing collided with a submerged cypress tree. He later stated the loss of engine power was due to fuel exhaustion. According to a mechanic who helped recover the airplane, both fuel tanks were drained and a total of approximately 1.5 gallons of fuel were recovered. The mechanic further reported that the total unusable fuel capacity for each fuel tank is 1.5 gallons.
Probable cause
The pilot's inadequate in-flight planning/decision which resulted in fuel exhaustion. The pilot's inadequate preflight planning/preparation to ensure an adequate fuel supply is a contributing factor.

- 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, coordinates. 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.
