Analysis

The eng lost power when the acft was on final apch to land. The plt stated that he then switched fuel tanks, activated the electric fuel boost pump & worked the related wobble pump as fast as he could, but was unable to restore eng power. Subsequently, the acft crashed into a building and cartwheeled into a parking lot. An exam of the wreckage revealed the left fuel tank was empty. About 10 gal of fuel was remaining in the right tank & an undetermined amount of fuel was in the aux tank. The wobble pump/fuel selector assembly's tank selector valve, pn 35-924068, was modified, but was not installed in accordance with the manufacture's specification. The selector's detent ball, PN35-921166, was missing & the assembly's spring was riding on the valve. Also, the assembly's housing, pn 35-921185, was damaged. In this condition, the plt could not determine the exact position of the selector valve. An exam of the acft revealed it had crashed in a steep nose down, left wing low attitude.
