The commercial pilot reported he had made several passes with the helicopter during an aerial application flight. On the downwind leg of the accident approach, the engine shuttered violently, then quit. The pilot performed a run-on landing. During the landing sequence the main rotor blade made contact with the tail boom of the helicopter, severing the tail rotor gearbox. The engine of the helicopter was externally inspected, and the aft section of the engine case was ruptured. The engine was disassembled, and the number 3 piston connecting rod was discovered to be broken.
Probable Cause: The failure of a piston connecting rod during an aerial application, which resulted in a total loss of engine power and subsequent forced landing.
