## Analysis

DURING TAKEOFF, THE ENGINE LOST POWER AFTER THE PLT STARTED TO MAKE A TURN AT APRX 500 FT AGL. AN EMERGENCY LANDING WAS MADE IN A PLOWED FIELD WITH THE GEAR & FLAPS RETRACTED. AFTER TOUCHDOWN, THE ACFT SLID APRX 100 YARDS, THEN STOPPED IN A CANAL. AN INVESTIGATION REVEALED THAT THE ACFT HAD JUST RECEIVED MAINTENANCE ON THE MAGNETOS FOR COMPLIANCE OF AN AD WHICH REQUIRE REPLACEMENT OF A GEAR. AN ENGINE TEARDOWN REVEALED THAT A RETAINING SCREW FOR THE CAM IN THE MAGNETO WAS LOOSE. REPORTEDLY, THE PASSENGER WAS NOT WEARING A SHOULDER HARNESS & RECEIVED A FRACTURED STERNUM & MULTIPLE BRUISES, ESPECIALLY ABOUT THE HEAD.
