## Analysis

THE ACFT COLLIDED WITH A TREE DURING A FORCED LANDING AFTER A POWER LOSS ON TAKEOFF. THE PILOT HAD A LOAD OF 125 GALLONSOF A FUNGICIDE FOR SPRAYING TREES WHEN THE ENGINE QUIT AT ABOUT 100 FT AGL. THE LOAD WAS DUMPED AND THE ACFT WAS TURNED TO THE RIGHT FOR A LANDING IN AN OPEN FIELD. THE ACFT CONTACTED A TREE ON THE BOUNDARY OF THE FIELD AND ROTATED ABOUT 45DEGREES TO THE RIGHT. IT THEN LANDED AND BOUNCED AROUND AND ENDED UP HEADING NORTH IN AN UPRIGHT POSITION. A POST ACCIDENT EXAMINATION DETERMINED THAT THE ENGINE WOULD ONLY RUN WITH THE ELECTRIC FUEL BOOST PUMP ON. THE ENGINE DRIVEN FUEL PUMP (PN 638154-1) HAD SEIZED AND THE DRIVE SHAFT HAD SHEARED. THE SEIZURE OCCURRED AT THE SHAFT SEAL (P/N 13507).
