Analysis

At the end of a sightseeing flight, the pilot approached the landing zone with a tail wind and gusting wind conditions at 30 knots. Approximately 20-30 feet AGL, a gust of wind caught the helicopter which veered off and skimmed over power lines in the close proximity to the landing zone. Power was applied and the helicopter gained 20-30 feet and continued on to land hard in the open field. There were no reported mechanical failures or malfunctions with the helicopter at the time of the accident.
