## Narrative

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

(.4) THE PILOT REMAINED IN THE TRAFFIC PATTERN TO PRACTICE TOUCH AND GO LANDINGS. AT APPROXIMATELY THE POINT WHERE THE HELICOPTER WOULD TURN ONTO THE BASE LEG, ROTOR RPM BEGAN TO DECAY (95%).  THE PILOT TURNED TOWARDS THE RUNWAY AND BEGAN AUTOROTATION.  DURING THE DESCENT, THE PILOT MANAGED TO AVOID HOUSES AND POWERLINES.  THE HELICOPTER STRUCK THE GROUND TAIL FIRST, THEN ROLLED OVER ON ITS LEFT SIDE.  THE ENGINE WAS LATER FUNCTIONALLY TESTED AND, DESPITE IMPACT DAMAGE TO THE CRANKSHAFT, OPERATED NORMALLY.
