Aircraft Accident/Incident Report

Eupora, Mississippi 39744

NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

A loss of engine power due to fuel contamination of the helicopter’s fuel supply.
