About ten minutes after departing on a repositioning flight, the aircraft's engine experienced a total power loss. The pilot elected to autorotate to an open farm field, where the helicopter touched down on frozen muddy terrain. As the helicopter slid forward, it impacted a ridge of frozen dirt, resulting in the collapse of the skids. When the skids collapsed, the main rotor impacted the tail boom, and the aircraft sustained substantial damage. An inspection of the aircraft revealed no anomalies in any of its systems, and no contamination or water accumulation was found in its fuel. The reason for the loss of power was not determined.
Probable Cause: loss of engine power for undetermined reason(s). A factor relating to the accident included a dirt berm/ridge in the field where the pilot executed the forced landing.
