According to the commercial pilot, he was receiving a checkride to become a flight instructor. During a full stop autorotation practice, as the pilot began a slow flare to slow the helicopter, the helicopter ballooned, he lost control of the helicopter, and it pitched up to the left. During an attempt to regain control of the helicopter, the tailboom struck the ground, and the helicopter rolled over. According to the designated pilot examiner giving the checkride, it was the commercial pilot's third checkride attempt. The pilot's previous checkrides resulted in an unsatisfactory performance and termination of the evaluation due to the pilot’s slow reaction times.
