Analysis
During cruise flight pilot heard loud bang from right engine and right propeller feathered. Aircraft was diverted and landed with no further damage and no injuries to the pilot. Subsequent teardown of engine revealed fractured connecting rod. Examination of rod revealed fatique fracture due to surface inclusion in rod shank. Inclusion resulted from oxides which formed during heat treatment and were not completely removed prior to shot peening.
