Probable cause
a hex nut on the cyclic flight control pushrod bolt had backed off for undetermined reason(s) and allowed the bolt to become disconnected from the control yoke teeter block, resulting in a loss of cyclic control and subsequent roll over during an emergency landing.

The pilot stated he was on base turn to final for a fly bye, when he experienced a 1 to 1 vertical vibration. He informed the tower that he was going to land, and started a deceleration. The helicopter veered to the right, and the pilot applied left antitorque pedal. The nose started to tuck down, then the helicopter collided with the ground and rolled over on its right side. Examination of the helicopter flight control system revealed a hex nut backed off the cyclic flight control push rod bolt, and the bolt became disconnected from the control yoke teeter block. This resulted in a loss of cyclic control.
