## Narrative

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

(-23) THE PILOT CFI ^PRIVACY^ OF THE PHOENIX POLICE DEPT, WAS GIVING HELICOPTER FLIGHT INSTRUCTION TO FELLOW POLICE OFFICER ^PRIVACY D^. DURING THE FLIGHT THE CFI WAS INSTRUCTING THE STUDENT IN HOVERING AUTOROTATIONS, AFTER PERFORMING THE MANEUVERS THEY RETURNED TO THE DVT AIRPORT. UPON ARRIVAL THEY PRACTICED ADDITIONAL MANEUVERS AT THE POLICE DEPARTMENT SITE AND TAXIED TO THE HELICOPTER PAD LOCATED IN FRONT OF THE POLICE DEPARTMENT HANGAR WHERE A MAINTENANCE PERSONNEL NOTED DAMAGE TO THE TAIL BOOM JUST FORWARD OF THE VERTICAL FIN AND INSTRUCTED THE CREW OF THE HELICOPTER TO SHUT DOWN. AN INSPECTION REVEALED DAMAGE TO THE TAIL ROTOR FAIRING, TAIL ROTOR DRIVE SHAFT, DRIVE SHAFT COUPLING AND EVIDENCE OF STRIKE ON THREE OF THE MAIN ROTORS. AN EVALUATION OF THE FOUR MAIN ROTORS BY AGUSTA FOUND ALL FOUR BLADES ARE OUT OF ACCEPTABLE DEFLECTION TOLERANCE AND MUST BE SCRAPED. IT IS ASSUMED THAT THE DAMAGE WAS A RESULT OF LOW ROTOR RPM DURING THE DEMONSTRATION OF HOVERING AUTOROTATIONS RESULTING IN THE BLADE STRIKES ON THE TAIL BOOM AND DRIVE SHAFT.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
