## Narrative

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

(-23) DURING STUDENT TRAINING IN AUTOROTATION MANUEVERS THE STUDENT LET THE RPM GO LOW DURING THE APPROACH. THE INSTRUCTOR ATTEMPTED TO CORRECT THE SITUATION BUT MET RESISTANCE FROM THE STUDENT. THE AIRCRAFT LANDED HARD AND SKIDS COLLAPSED. THE HELICOPTER SLID FOR OVER 150 FEET BUT STAYED UPRIGHT. THE SEAT PANS WERE TOTALLY FLEXED DOWNWARD IN THE FRAME AND THE STRUCTURE OF THE HELICOPTER WAS BENT AND BROKEN.

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