The pilot, a volunteer with the sheriff's department, was conducting proficiency training when the accident occurred. According to the pilot, he had completed three approaches and was on the fourth approach when he encountered a dust devil along the approach path. After encountering the dust devil, when several feet above the ground, the helicopter yawed to the right. In an effort to recover from the yawed condition, the pilot instantly rolled off the throttle control, and the helicopter collided with the ground. No mechanical problems were reported with the helicopter by the pilot. The post-accident examination of the helicopter also did not disclose any mechanical problem.
Probable Cause: The in-flight encounter with weather that resulted in the loss of tail rotor control. The pilot failed to maintain directional control and the helicopter collided with the ground.
