During a departure, the pilot climbed to 500 feet, reduced power, and switched fuel tanks. The engine lost power about one minute later. Unable to restart, the pilot performed a forced landing during which the right wing struck powerlines. Subsequent examinations found no mechanical or fuel system abnormalities.

Incident Narrative

The pilot initiated the flight by departing from an airstrip. He climbed to 500 feet above ground level, then reduced engine power. He activated the fuel transfer pump and switched the fuel selector from the left to the right fuel tank. Approximately one minute after that fuel selection, the engine ceased to produce power. The pilot returned the fuel selector to the left tank, but was unable to restart the engine. Consequently, he performed a forced landing. During the forced landing, the right wing struck powerlines.

Investigation

Post-incident, the engine was examined and run; no mechanical malfunctions were detected. An inspection of the airplane's fuel system also revealed no abnormalities.
