Investigating agency: NTSB
Narrative:
The pilot reported that after preflighting the helicopter he hovered the helicopter to a location where he 'hot fueled' out of a fuel service tank that was in the flatbed of a pickup. The pilot remained at the controls while the hot refueling occurred. The pilot did not check for fuel contamination after the helicopter was hot refueled with 8 to 10 gallons of fuel. He reported taking off to relocate the helicopter to the field where agricultural spraying operations were to be conducted. He flew about 1/2 mile and was about 100 feet agl traveling at 50 knots when the helicopter yawed to the left and the low RPM light illuminated. The engine quit and he entered an autorotation. He pulled some collective to avoid a tree. He reported that he completed the autorotation, but the helicopter was in a high rate of descent with very little blade inertia when he impacted the ground. An inspection of the helicopter revealed that the fuel sump, carburetor, and adjacent fuel lines were contaminated with water. A fuel sample was taken from the bottom of the fuel service tank located on the back of the pickup, and it was contaminated with water.

Probable Cause: the engine quit due to water contamination of the fuel and the pilot's inadequate preflight.
