Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, shortly after takeoff, the helicopter encountered a dust devil from the right side, which caused the helicopter to yaw right and descend. Despite the pilot’s best attempt to control the helicopter, it struck terrain. The helicopter sustained substantial damage to the tail boom. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
