## Narrative

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

HELICOPTER LANDED HARD, THE TAIL BOOM BROKE OFF, AND THE ROTOR SUSTAINED DAMAGE. (-23) PIC ERIK GILETTO, ACCOMPANIED BY STUDENT PILOT GILAD HOROWITZ, HAD BEEN PRACTICING AUTOROTATIONS AT RAMONA AIRPORT. UPON ENTERING A 180 DEGREE AUTOROTATION, GILETTO HE EXPERIENCED A NOSE DOWN ATTITUDE AND A ROLL TO THE RIGHT, ACCOMPANIED BY A LOW ROTOR RPM WARNING HORN (97%). GILETTO STATES HE RECOVERED TO A NORMAL AUTOROTATIVE ATTITUDE, FOLLOWED BY ANOTHER NOSE DOWN, ROLL TO THE RIGHT REACTION, WITH A RAPID ROTOR RPM REDUCTION (73%). AS THE HELICOPTER DESCENDED WITH LOW ROTOR RPM, GILETTO'S ATTEMPT TO CUSHION THE LANDING WAS UNSUCCESSFUL; THE HELICOPTER CONTACTED THE TAXIWAY WITH A HARD IMPACT, CAUSING THE LEFT SKID LANDING GEAR TO COLLAPSE SIMULTANEOUS WITH THE MAIN ROTOR SEVERING THE TAIL BOOM. THE HELICOPTER CAME TO REST ON IT'S LEFT SIDE ON THE TAXIWAY. GILETTO AND HOROWITZ WERE UNINJURED AND THERE WAS NO POST CRASH FIRE.
