The pilot stated that he had completed an aerial application run in the airplane and began a left turn to return for another aerial application run. However, shortly after he began the maneuver, the airplane's engine lost total power. The pilot performed a forced landing to a field, during which the airplane nosed over. Examination of the radial engine revealed that the No. 1 cylinder k-pin had failed, resulting in significant internal engine damage and the loss of power. Further examination of the failed k-pin revealed that it had fractured near its center oil journal, and the k-pin fracture marks exhibited damage consistent with fatigue.
Probable Cause: The total loss of engine power due to the fatigue failure of the k-pin associated with the No. 1 cylinder.
