## Analysis

THE OWNER OF THE HOME BUILT AIRCRAFT WAS CHECKING OUT THE OTHER PILOT WHO WAS SECOND-IN-COMMAND (SIC). THE SIC ALSO HAD A HOME BUILT OF THE SAME MAKE AND MODEL. THE OBJECTIVE WAS TO PROVIDE FAMILIARIZATION TO THE SIC. DURING AN APPROACH TO LAND, THEY ELECTED TO GO AROUND AFTER OBSERVING ANOTHER AIRCRAFT ON THE RUNWAY. DURING THE GO-AROUND, THE ENGINE LOST POWER AND A FORCED LANDING WAS MADE IN A PLOWED FIELD. AFTER TOUCHDOWN, THE PLANE BEGAN TO COME APART, THEN FLIPPED OVER. BOTH PILOTS RECEIVED BROKEN NECKS, THE OWNER WAS PARALYZED FROM THE WAIST DOWN. AN INVESTIGATION REVEALED THAT THE CRANKSHAFT HAD FAILED AT THE CRANKARM BETWEEN THE #3 AND #4 CYLINDER CRANKPINS. THE ENGINE HAD 146 HRS TOTAL FLYING TIME.
