The pilot was taking off in variable winds in a helicopter that was near its maximum certified gross weight. Just as the aircraft started to move forward out of a hover, the wind shifted from a headwind to a tailwind gust. The pilot was unable to adequately compensate for the unfavorable wind change, and the helicopter impacted the terrain with sufficient force for the main rotor to come in contact with the tail boom.
