What happened
Approximately 45 minutes into the flight, the Certified Flight Instructor (CFI) began a demonstration of a power recovery autorotation. Following the demonstration, the instructor allowed the student to attempt the maneuver. The CFI positioned himself near the flight controls to provide guidance and instructions on necessary actions during the procedure.
After entering the autorotation, the CFI monitored the engine and rotor RPMs, noting that they appeared to be within normal parameters. When the aircraft reached an altitude of approximately 10 to 15 feet, the CFI instructed the student to apply engine power. However, the engine failed to respond to throttle movement. The CFI then took control of the aircraft as the engine appeared to have failed. The helicopter subsequently performed a hard landing and rotated 180 degrees upon impact.
There were no injuries reported following the incident.
