Analysis narrative
The pilot, who held an expired student certificate, had the right fuel tank refueled with 88 octane automotive gas before departing for the night flight with three passengers. The left fuel tank was empty. During the initial climb out from the airport, a total loss of power occurred and the pilot was forced to land on a slope in a canyon. Post accident examination of the airplane and powerplant did not reveal any mechanical anomalies. However, the fuel selector handle was found positioned on the left fuel tank. The powerplant had been converted under an stc to use automotive gasoline.
