DURING FINAL APCH THE ENG QUIT. THE PLT THEN ATTEMPTED TO LAND THE ACFT ON A ROAD, DURING WHICH, IT COLLIDED WITH TREES. INSPECTION OF THE ACFT REVEALED THAT THE ADJUSTING SCREW ON THE ENG DRIVEN FUEL PUMP BACKED OUT APRX 8 TURNS. BENCH TEST OF THE PUMP REVEALED THAT THE FUEL FLOW FROM THE OUTLET WAS HIGHER THAN THE LIMITS SPECIFIED BY THE MANUFACTURER DUE TO THE COUNTER-CLOCKWISE ROTATION OF THE SCREW. ACCORDING TO A FAA INSPECTOR THE ENGINE COULD POSSIBLY QUIT IF THE MIXTURE CONTROL WERE PLACED IN THE FULL RICH POSITION AS IS THE CASE DURING APCH, DUE TO EXCESSIVE FUEL.
