- 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 contamination; Fuel starvation
- 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
DURING THE PREFLIGHT, THE PILOT FOUND THE LEFT WING FUEL CAP OFF. HE STATED HE DRAINED ALL THREE FUEL SUMPS, ROCKED THE WINGS, AND DRAINED THE SUMPS AGAIN. HE STATED THE ENGINE STARTED WITHOUT ANY PROBLEM AND HE TAXIED THE AIRPLANE TO THE FUEL PUMP AND REFUELED THE AIRPLANE. HE STATED THAT AFTER THE REFUELING HE DRAINED THE FUEL SUMPS AGAIN. DURING THE FLIGHT THE ENGINE BEGAN TO LOSE AND THEN REGAIN POWER. THE PILOT DECIDED TO RETURN TO THE DEPARTED AIRPORT AND WHILE EN ROUTE THE ENGINE LOST POWER. THE PILOT MADE A FORCED LANDING AND COLLIDED WITH TREES IN A WOODED AREA SHORT OF THE AIRPORT. POSTACCIDENT EXAMINATION OF THE FUEL SYSTEM REVEALED WATER IN THE FUEL. THE ENGINE WAS STARTED SEVERAL TIMES AND THE ENGINE QUIT EACH TIME. AFTER EACH ENGINE FAILURE, WATER WAS FOUND IN THE CARBURETOR BOWL. ONCE THE WATER WAS DEPLETED FROM THE FUEL SYSTEM, THE ENGINE RAN WITH NO ANOMALIES NOTED. THE PILOT STATED THAT THE AIRPLANE WAS LAST FLOWN ABOUT 7 DAYS PRIOR TO THE ACCIDENT. HE SAID IN THOSE 7 DAYS THERE WAS PRECIPITATION IN THE AREA. THE NIGHT PRIOR TO THE ACCIDENT, TEMPERATURES WERE BELOW FREEZING.
Probable cause
The pilot's inadequate preflight inspection which failed to detect water-contaminated fuel.

- 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.
