## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

AT ABOUT 1:30 ON TUESDAY AUGUST 18, 2015, THE PILOT TOOK OFF WITH 25 GALLONS OF FUEL AND 80 GALLONS OF CHEMICAL TO SPRAY A BEAN FIELD 7 MILES EAST OF CRESCO, IA. ABOUT 5 MINUTES INTO THE SPRAY RUN AT ABOUT 5 FEET ABOVE THE FIELD THE ENGINE FAILED.  THE PILOT STATED THAT HE NOTICED THE MAIN ROTOR RPM BLEEDING OFF AND EXECUTED AN AUTO ROTATION TO A WATER WAY ON THE SIDE OF A HILL. UPON TOUCH DOWN ON THE UNLEVEL TERRAIN, THE MAIN ROTOR CONTACTED THE TAILBOOM AND IT SEPARATED FROM THE AIRCRAFT.  ONCE THE BLADES STOPPED SPINNING, THE PILOT SHUT THE FUEL VALVE OFF AND EXITED THE HELICOPTER. THE HELICOPTER WAS SITTING UP RIGHT.
