The flight was level at 17,500 feet msl when 40 minutes into the flight the engine began to run extremely rough. This lasted for about 10 to 15 seconds when the engine abruptly stopped. Postaccident examination of the engine revealed that the number 1 connecting rod failed causing a catastrophic failure of the engine. Subsequent examination of the engine revealed that the number 1 main bearing oil supply hole had been blocked from supplying oil to the number 1 connecting rod. Examination of the number 1 main bearing halves revealed that there were operational movements indicated on a bearing half. Evidence was found to indicate the half had fractured/disintegrated and blocked the oil supply hole. The number 1 connecting rod then failed from oil starvation.
