The instructor pilot reported that he was conducting a commercial checkride. He and the dual student, flying the helicopter, were in a hover approximately 4-5 feet above the ground and oriented on a 190-degree heading. While at that location, the helicopter began to yaw and drift to the left. The instructor pilot said he put in opposite pedal but the helicopter continued to yaw and drift to the left. The helicopter struck the ground, left skid low on a 30 to 45 degree down angle. The instructor said he took control of the helicopter and attempted to maintain a level attitude. The helicopter bounced and then struck nose low and rolled to the right. An examination of the helicopter systems revealed no anomalies. A Federal Aviation Administration inspector on the scene said conditions were very windy. He also said that when considering the wind conditions and the way the helicopter impacted the ground, the winds may have contributed to the accident. The wind conditions reported just before the accident were 190 degrees at 8 knots with gusts to 15 knots.
