DURING THE TAKEOFF INITIAL CLIMB SMOKE CAME FROM THE ENGINE AND A POWER HESITATION OCCURED. THE PILOT DUMPED THE LOAD AND TURNED THE AIRPLANE TOWARD THE AIRPORT. AS MORE SMOKE CAME FROM THE ENGINE, A TOTAL LOSS OF POWER OCCURRED. DURING THE FORCED LANDING THE AIRPLANE CROSSED A TREE LINE AND LANDED IN A RICE FIELD. DURING THE LANDING ROLL, THE MAIN GEAR HIT A LEVEE AND THE AIRPLANE CAME TO REST INVERTED. EXAMINATION OF THE ENGINE AND ACCERSSORIES REVEALED THE SUPERCHARGER IMPELLER P/N 12788 WAS DAMAGED WHERE THE BLADES HAD CONTACTED THE HOUSING. THE IMPELLER BEARING P/N 288943 HAD FAILED AND ALLOWED THE IMPELLER TO BE DESTROYED RESULTING IN A COMPLETE LOSS OF THE ENGINE POWER.
