Analysis

On a flt from fair oaks, CA, to reno, NV, a flt of about 1 hr 15 mins, the acft experienced a total power loss. The plt asked the pax to select the other fuel tank. The selctor handle was not attached to the valve. But the pax located the handle and turned the valve. This action did not aid in restarting the engine. During a forced landing at night, the acft struck a tree, an electric cable, then impacted the ground. An investigation disclosed that the fuel selector valve was in the 'off' position. Beech service instruction no 1095, which provided for stops on the fuel valve to preclude inadvertent selection of the off position had not been accomplished. The acft had flown 6 hrs previously without refueling. Normal endurance is 6-1/2 hrs. About 6 gals of fuel remained in the right tank. The plt, a former army aviator, held no FAA plt ratings. A toxicology test of the plt's blood showed an alcohol level of 0.177%.
