When the aircraft altitude was about 30 feet, the pilot felt that the aircraft yawed to the right then decided to make a go around. The pilot pulled the collective slightly and felt the aircraft progressively yawed to the right. The pilot maintained the collective and the cyclic position then the aircraft attitude was uncontrolled nose down. Prior to impact, the pilot recovered by pulling the collective and cyclic to level the helicopter and the helicopter touchdown on the grass about 30 meters before reaching intended landing point.The Operation Manual Part B describe the loss of tail rotor thrust in forward flight is usually indicated by nose right yaw which cannot be corrected by applying left pedal. The OM Part B also describe the procedure Loss of Tail Rotor Thrust was immediately close throttle then perform autorotation landing.The recovery action taken was different with the procedure describe in the Operation Manual, therefore KNKT recommends to review pilot training to ensure pilot recognition to the aircraft problem and able to perform correct recovery procedure.
