## Narrative

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

(-23) PILOT STARTED HELICOPTER. WHILE ENGINE WAS RUNNING THE PILOT EXITED THE HELICOPTER TO UNPLUG AN AUXILIARY POWER UNIT. PILOT MOVED AUXILIARY POWER UNIT AWAY FROM THE HELICOPTER. AS THE PILOT WAS WALKING AWAY FROM THE HELICOPTER, A GUST OF WIND SWUNG THE TAIL APPROXIMATELY 90 DEGREES TO THE LEFT CAUSING THE HELICOPTER TO MOVE BACKWARDS UNDER ITS OWN POWER. THE HELICOPTER WENT BACKWARDS OFF AN EMBANKMENT UNDER ITS OWN POWER AND CAME TO REST ON ITS RIGHT SIDE WITH THE NOSE FACING DOWNHILL. THE HELICOPTER SUSTAINED SUBSTANTIAL DAMAGE.
