The more experienced pilot was occupying the rear control position, which did not have tail rotor control pedals, while another pilot flew the aircraft. During the approach to land the pilot in the rear seat became concerned when the airspeed decayed and he pushed the cyclic control forward to initiate a go around. The aircraft yawed to the right, control was lost and the aircraft struck the ground heavily, coming to rest on its right side. The inexperienced pilot occupying the front seat had been surprised when the rear seat pilot had taken control during the approach. Although he had been instructed to apply left pedal, it is likely that his delay in doing so, prevented control from being regained before the helicopter struck the ground. Inspection of the aircraft revealed that forward cyclic control movement was limited by incorrect rigging. This may have also contributed to the loss of control.
