Analysis

The pilot stated that he intended to practice autorotations and hovering at the airport. Upon arriving at the airport practice area, he began 360-degree hovers. During one of the hovers, he lost control of the helicopter and it landed hard. Wind gusts were reported at the time of the accident which the pilot thought contributed to the loss of helicopter control. During the hard landing, the skids split and the tail boom was bent. The pilot reported no mechanical malfunctions.
