Narrative:During takeoff from the refueling pad, the helicopter's engine lost power and the pilot attempted an autorotation. Because the aircraft did not yet have sufficient airspeed or altitude to complete a successful autorotation, it landed hard and the main rotor blades flexed downward and impacted the tail boom. It was later determined that water contamination had accidentally been transferred from a portable refueling barrel to the aircraft's fuel system during hot refueling (with engine still running). It could not be determined how water was introduced into the refueling barrel.
Probable Cause: A loss of power due to water contamination of the fuel. Factors include the inability of the helicopter to perform a successful autorotation immediately after takeoff.
