NTSB narrative
While on base leg of the traffic pattern at the destination airport, the airplane lost engine power. The pilot completed the emergency checklist but was unable to restore engine power. During the forced landing near the airport, the airplane collided with several trees resulting in substantial damage. An engine test run was conducted while the motor was still attached to the airframe, utilizing an external fuel source attached to the left side fuel system. The engine started and accelerated to 2,400 rpm. Dark black smoke was observed from the exhaust system and the engine ran rough at full mixture. The engine ran smooth when leaned, and the leak rate on the metering unit return to the fuel pump was higher than normal. The exact cause of the loss of engine power could not be determined.
Probable cause
A loss of engine power for undetermined reasons.

- 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 2010-11-18.
