That's everything on file so far — TailWiki checks the FAA registry daily and adds new entries as N646H's record changes.
The pilot of the helicopter reported that, after completing an aerial application, he returned to the mix vehicle for an additional load. While reloading the helicopter, he noticed the wind direction was changing and “blowing harder” and may have shifted to a quartering tailwind. During takeoff from the mix vehicle, the engine and main rotor blade rpm started to decay. He aborted the takeoff and made a run on landing to an open field near the mix vehicle. During the landing the main rotor blades tilted aft and severed the tailboom. The helicopter sustained substantial damage to the tailboom.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
