NTSB narrative
The pilot reported that he adjusted the engine carburation system on the airplane prior to the flight. While approaching to land, the pilot reduced power and the engine lost total power. The pilot made several attempts to restart the engine but was unsuccessful. The airplane lost altitude and was substantially damaged when it impacted the roof of a shed. During a postaccident engine examination, no mechanical anomalies were discovered internally within the engine. The carburetors were removed, and a small cut was discovered on a fuel line along with dry rot on the rubber boot for the front carburetor manifold. The engine then was removed and placed on another airframe for a test run. The test run was completed successfully with no anomalies noted. Based on these findings, the reason for the loss of engine power could not be determined.
Probable cause
A total loss of engine power for reasons that could not be determined.

- 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.
