NTSB narrative
The pilot reported that while abeam the runway numbers on a left downwind in preparation to land after performing a skydiving drop, the engine lost power and then totally quit. The pilot performed a forced landing to a two-lane highway. While maneuvering to land, the airplane collided with a light pole and came to rest inverted, substantially damaging the airplane.
Postaccident examination of the airplane revealed water- and debris-contaminated fuel in the airframe fuel filter bowl and water-contaminated fuel in the fuel manifold and fuel pump. Also, the fuel inlet screen was mostly clogged with what appeared to be dirt and corrosion. The engine most likely lost power due to fuel contamination, as the fuel filter, fuel manifold, and fuel pump all tested positive for water.
Probable cause
A total loss of engine power due to fuel starvation as a result of contamination in the airplane’s fuel system.

- 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, cause areas. 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.
