Analysis

The commercial pilot reported that he intended to take the helicopter out to practice hover flight. As he started to lift the helicopter off of the ground and move towards the grass, he lost control of the helicopter and it impacted the ground. An examination of the helicopter revealed substantial damage to the tail boom and main rotor. The pilot attributed his inability to maintain control of the helicopter to a stronger than expected crosswind and that he had not flown a helicopter for about 19 years.
