Read the full NTSB narrative

While in cruise flight, the pilot noticed a loss of oil pressure which was followed by a total loss of engine power. He elected to ditch the airplane in a lake as no other suitable forced landing site was available. An examination of the engine revealed the that the #4 connecting rod had separated from the crankshaft at the end cap. The rod end cap bolts had separated from the cap, and exhibited evidence of necking and heat distress. The #4 rod journal also exhibited evidence of heat distress. The bearings associated with the #4 rod journal were destroyed. All other rod journals and all of the main bearing journals did not exhibit evidence of heat distress or lack of lubrication.
