NTSB Narrative Summary Released at Completion of Accident

The pilot landed in a flat grass covered field for the purpose of removing a long line and bambi bucket used in firefighting operations. Following touchdown, the pilot rolled the throttle to flight idle, and applied the frictions for the cyclic and collective. The wind conditions at the time were from 060 degrees at 19 knots gusting to 25 knots. After the pilot exited the helicopter, a gust of wind caught the unattended rotor disk, and tilted it, causing the helicopter to tilt rearward on its skids. The pilot returned to the controls just as the tail rotor made contact with the ground. He leveled the helicopter, brought the engine back to flight idle, and initiated a hover. The pilot stated that after he performed several pedal turns and noticed no control hindrance, he elected to return to Kahului. The helicopter sustained substantial damage consisting of damaged tail rotor blades and a bent and twisted tail rotor system drive shaft.

NTSB Probable Cause Narrative

the pilot's failure to shut down the engine prior to exiting the helicopter resulting in the tail rotor contacting the ground. A contributing factor was the gusting wind conditions present at the accident site.
