Probable cause & findings

THE STUDENT PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL, FAILUE TO MAINTAIN CORRECT ROTOR RPM, AND IMPROPER USE OF THE FLIGHT CONTROLS.

Factual narrative

THE PILOT STATED THAT WHILE ATTEMPTING TO LAND, HE REALIZED HIS ALTITUDE AND LANDING SPEED WERE HIGH AS WERE THE ENGINE AND ROTOR SPEEDS. HE REDUCED THE THROTTLE, THEN HE LOST CONTROL, AND THE HELICOPTER BEGAN TO SPIN. BEFORE IMPACTING THE GROUND, HE RAISED THE COLLECTIVE CONTROL AND PULLED THE CYCLIC STICK, BUT FAILED TO PUSH THE RIGHT PEDAL TO STOP THE SPINNING ACTION.
