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.
