Read the full NTSB narrative

AS THE AIRCRAFT WAS CLIMBING FROM TAKEOFF, THE PILOT NOTICED AN UNUSUAL ENGINE NOISE & OIL PRESSURE FLUCTUATIONS. WHEN HE REALIZED THE AIRCRAFT WOULD NOT REACH THE AIRPORT, HE SHUT DOWN THE ENGINE & MADE A WHEELS UP LANDING IN A NEWLY PLANTED CORN FIELD. EXAMINATION OF THE ENGINE REVEALED EVIDENCE OF OIL STARVATION OF THE #4 ROD BEARING, THE #5 ROD BEARING & THE MAIN BEARING, THEN SUBSEQUENT FAILURE OF THE #5 ROD. THERE WAS EVIDENCE THAT THE OCCURRENCE WAS INITIATED BY SLIPPAGE OF A BEARING.
