NTSB narrative
During an aerial application flight, the helicopter's engine lost power while flying about 50 feet above the ground. The pilot stated that the helicopter dropped straight down, and that the rotor stopped turning during the descent. The helicopter was substantially damaged during the impact sequence. A postaccident examination of the helicopter's fuel system revealed a brown contaminate, of a density greater than jet fuel. The contaminate was present in several airframe and engine fuel filters and on the engine fuel nozzle. Examination of the dual use truck that was used to service the helicopter with fuel and herbicide revealed that the fuel filter between the Jet-A fuel tank and the fuel delivery hose was also contaminated. A common trough that ran along the top of the fuel truck provided an area where any over flow of water used to fill the truck's herbicide tank could be introduced into the truck's Jet-A fuel tank through gaps in the fuel tank's cap seal.
Probable cause
A loss of engine power due to fuel contamination of the helicopter’s fuel supply.

- 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. 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.
