Primary finding
Probable cause
The pilot's failure to maintain control of the helicopter during flight, which resulted in the helicopter impacting terrain.
Investigator assessment
Analysis narrative
The pilot stated he was positioning the helicopter to have the sole passenger take a photograph of an animal and a settling with power condition occurred. The pilot stated that a gust of wind came from a nearby hill and began to push the helicopter toward the ground so the pilot conducted a running landing to an open field. During the landing, the pilot reported that the helicopter struck an anthill and rolled sideways. The helicopter sustained substantial damage to the tail boom. The pilot verified that there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

After multiple requests, the pilot did not turn in the National Transportation Safety Board Form 6120.1 Pilot/Operator Aircraft Accident/Incident Report as requested.
