Read the full NTSB narrative

The helicopter collided with the ground and rolled over following a loss of directional control while hovering. The student pilot performed a 90-degree pedal turn to the right. As he completed the turn he encountered a right crosswind and began to lose control of the helicopter. The helicopter yawed to the left and drifted into a run-up area. The student asked the certified flight instructor (CFI) to take control. The CFI applied left pedal, causing the left yaw to progress into a spin. Before he realized his mistake and made a corrective input, the helicopter hit the ground and rolled onto its left side. The CFI stated that the helicopter and engine had no mechanical failures or malfunctions during the flight. The Automated Surface Observation System located at the airport reported that the winds were from 240 degrees at 8 knots.
