Eurocopter AS350B3 crash near Poway, CA, United States

The pilot stated that he was approaching a landing zone on a flat pinnacle with a tailwind. The helicopter was in a slow, stable, shallow approach when it encountered an updraft within 50 feet of the landing area. When the helicopter flew out of the updraft, it abruptly descended to the ground. The helicopter contacted the ground in a flat orientation, and the impact buckled the tail boom and sheared the left landing gear skid off.
