NTSB Narrative Summary Released at Completion of Accident

The airplane was eastbound and descending from a cruising altitude of 13,500 feet for landing. The pilot said that during descent, the "cylinder number 1 failed, followed immediately by the failure of cylinder number 2, and within about 4 seconds a total seizure of the engine." The pilot made a forced landing in an alfalfa field, subsequently impacting a berm and substantially damaging the airplane. The engine was later disassembled and examined. The engine had seized and could not be turned because connecting rods 1, 2, 3, 4, 7, and 9 were found broken, and numbers 5 and 6 were found severely damaged. Connecting rod 8 was not broken or damaged. Metal contamination was noted in the push rod housings, oil sump, thrust cover and bearing; cam, cam rollers, cam drive gear and inspection hole; main case, and oil screen. According to the FAA inspector, there were indications that the #7 connecting rod had struck the crankcase between #6 and #7 cylinders, breaking the through bolts.

NTSB Probable Cause Narrative

failure of the #7 connecting rod, causing engine seizure. A contributing factor was the berm.
