The CFI's failure to prevent ground contact during hover, which resulted in a dynamic rollover.
NTSB narrative
The certificated flight instructor (CFI) stated that he was tasked with flying with the student the morning of the accident. He spoke with the student's regular CFI and was briefed on his progress and ability. The helicopter was taxied to a defined spot on the airport and he began teaching the student how to hover. Approximately 15 to 20 minutes into the flight, while still practicing hovering, the CFI felt the helicopter moving aft followed by a violent jolt. The helicopter rolled onto the left side and caught fire. A postaccident inspection of the helicopter revealed that the main rotor hub was fractured and the associated main rotor blade was in 2 pieces.
