## Narrative

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

(-23) ON AN INSTRUCTIONAL FLIGHT THE INSTRUCTOR PILOT ATTEMPTED TO DEMONSTRATE AN ABORTED MAXIMUM PERFORMANCE TAKEOFF TO THE STUDENT FLIGHT INSTRUCTOR FROM A HEIGHT OF APPROXIMATELY 150 FEET ABOVE THE SURFACE. THE INSTRUCTOR STOPPED THE FORWARD MOVEMENT OF THE AIRCRAFT AND INITIATED A DESCENT WHILE FLYING THE HELICOPTER BACKWARD. THE AIRCRAFT SETTLED UNCONTROLLABLY TO THE SURFACE, SIMULTANEOUSLY ROTATING APPROXIMATELY 250 DEGREES TO THE RIGHT WHEN THE AIRCRAFT CONTACTED THE SURFACE, THE LANDING GEAR FAILED AT THE UPPER ATTACHMENT FITTING FOR THE LEFT REAR SKID STRUT. THE AIRCRAFT ROLLED TO THE LEFT AND CAME TO REST ON IT'S LEFT SIDE. THE ROTOR BLADES APPEAR TO HAVE CONTACTED THE LEFT SIDE OF THE TAILBOOM AT A VERY HIGH PITCH ANGLE WITH LOW ROTATIONAL VELOCITY AND THE TAIL BOOM FAILED AT THE POINT WHERE THE MOST REARWARD SECTION OF THE TAIL BOOM IS JOINED. ONLY ONE TAIL ROTOR BLADE SHOWS SLIGHT DAMAGE. BOTH THE INSTRUCTOR PILOT AND THE STUDENT REPORTED TO FAA PERSONNEL THAT THE AIRCRAFT ENGINE DID NOT LOSE POWER AND THAT IT WAS OPERATING AFTER IMPACT UNTIL THE INSTRUCTOR PILOT SHUT IT DOWN.
