The pilot took off downhill with no wind. The wind shifted to the west to a tailwind of 10 to 12 knots. The pilot said he was "unable to gain effective translational lift" and he attempted to land with a forward speed of 5 to 6 mph. He attempted to stop the helicopter but in doing so, "the tail skid struck the ground at the same time the skids did. Then the aircraft lurched forward, causing the main rotor to come in contact with the tail boom." The tail boom was severed and the skids were broken torsionally from the airframe.
Probable Cause: The pilot's failure to attain translational lift and his improper flare. A contributing factor in this accident was the sudden wind shift.
