Incident Overview
During a training flight, a helicopter transitioned from a hover to a landing when the student pilot began to lose directional control. The certified flight instructor (CFI) attempted to take control of the helicopter but did not verify that the student had completely removed his feet from the anti-torque pedals.
Sequence of Events
The student's right foot remained in contact with the right anti-torque pedal. This caused the helicopter to spin to the right approximately two full rotations. The aircraft subsequently impacted the ground and rolled onto its side.
Pilot Actions
The student pilot was operating the helicopter at the time of the loss of control. The CFI's intervention was incomplete, as he failed to ensure the student's feet were clear of the pedals before assuming control.
