NTSB narrative
The helicopter was substantially damaged when it impacted terrain during takeoff. The pilot stated that the helicopter was to be loaded with one passenger in the left seat and a 167 lb part behind the pilot. The part was loaded onto the helicopter and the pilot was then informed that the passenger would not be riding in the helicopter. Because of a "time deadline," the pilot decided to fly the helicopter from the left seat instead of the right in order to "have a good lateral C.G." During takeoff, the pilot reported that the helicopter started "sinking toward the ground" and that he was "over controlling the cyclic." The helicopter's skids came in contact with tall grass and tipped "very far forward." The pilot tried to level the helicopter with the cyclic, the tail "fell rapidly," and the helicopter subsequently impacted terrain and rolled over on its right side. The pilot stated in his accident report that the accident could have been prevented had he taken the time to get help to move the load to the co-pilot's side. He reported that it would have solved his lateral C.G. problem and he would be flying the helicopter from his normal position.
Probable cause
The pilot's failure to maintain control of the helicopter, which resulted in impact with terrain during takeoff. A factor in the accident was the tall grass.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
