What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The aircraft was enroute from kankakee, IL to kokomo, IN at 3500 feet on a VFR flight plan. Several minutes into the flight, there was a slight uncommanded power change. While the pilot was keeping an eye on that problem, the oil pressure went to zero and the engine failed. The pilot declared an emergency. ATC pointed out the closest airport was about seven miles away. The pilot stated to ATC that he couldn't make that airport and would land on a bean field below. The aircraft sustained no structural damage on landing. The #2 connecting rod failed and fractured the top left portion of the engine causing the engine to fail. (-23 amendment) the number 2 connecting rod failed breaking the crankcase and knocking the left magneto from the mount. The rod showed friction welding to the crank prior to failure. The counterweight was damaged by impact with the rod. It appears the engine continued to operate briefly following the rod seizure. Overboosting of the engine by a faulty turbo charging system may have contributed to the connecting rod failure.
