A total loss of engine power for reasons that could not be determined.

NTSB analysis

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.
