NTSB narrative
All engine power was lost while the pilot was maneuvering at a low altitude during an aerial application flight. The pilot made a hard forced landing in an open field and bounced. Thereafter, the main rotor blades severed the tail boom. The accident occurred during the third aerial application flight. For the first flight he had refueled with 25 gallons of fuel, and the helicopter was carrying a full load of insecticide. On the second flight he took on only insecticide. On the third (accident flight), he again only took on insecticide. The pilot reported that his normal procedure is to refuel on the second flight, which he did not do. He reported that with 25 gallons of fuel on board he could fly about 20 minutes with a 10-minute reserve. The pilot acknowledged that he should have refueled after the second application, but failed to do so and experienced fuel exhaustion. No mechanical anomalies were reported with the helicopter.
Probable cause
The pilot's failure to refuel the helicopter, which resulted in fuel exhaustion.

- 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: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2005-09-22.
