## Narrative

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

(-23) PILOT WAS SPRAYING RAILROAD RIGHT-OF-WAY AND THEN MADE A CYCLIC CLIMB WITH A PEDAL TURN. THIS PEDAL TURN PLACED THE HELICOPTER IN A DOWN WIND CONDITION WITH THE WINDS AT ABOUT 20 KTS. THE AIRCRAFT STRUCK THE GROUND HARD AND ROLLED ONTO ITS RIGHT SIDE.

## The NTSB's investigation of this event (1)
