Narrative:
DURING THE FINAL APPROACH SEGMENT OF A PRECISION APPROACH RADAR (PAR), THE AIRCRAFT'S LEFT ENGINE HAD A TOTAL LOSS OF POWER. THE PILOT SECURED THE ENGINE AND THEN NOTICED THE RIGHT ENGINE LOSING POWER. THE PILOT SECURED THE RIGHT ENGINE AND ENTERED A POWER OFF FORCED LANDING. HE ATTEMPTED TO LAND ON AN INTERSTATE HIGHWAY. DURING THE DESCENT, THE AIRPLANE'S RIGHT MAIN LANDING GEAR CONTACTED THE TOP OF A BUS. THE PILOT CONTINUED THE DESCENT UNTIL THE AIRCRAFT TOUCHED DOWN ON THE HIGHWAY. THE AIRCRAFT COLLIDED WITH A LANE DIVIDER DURING THE LANDING ROLL AND CAME TO A REST. AN FAA SAFETY INSPECTOR EXAMINED THE AIRCRAFT ON SCENE AND COULD NOT FIND ANY EVIDENCE OF FUEL IN ANY OF THE AIRCRAFT'S FUEL TANKS.
