Analysis

While en route to reposition the helicopter to another farm, the eng lost power. The plt reported that during an autorotation, the main rotor lost some RPM as he stretched his glide to avoid a fence. As the helicopter touched down on uneven terrain, the main rotor blades struck the tail boom. An exam of the eng revealed that a connecting rod had failed.
