The helicopter was conducting agricultural spraying operations when, during a reversal turn, tailrotor control was lost. The helicopter hit the ground. The helicopter had a previous maintenance history of a forward tailrotor driveshaft nut becoming loose. The cause of this was traced to incorrect assembly of the spline adapter, which is fitted to the input pinion of the tailrotor gearbox. This in turn caused damage to the driveshaft, allowing movement of the driveshaft and a loss of drive train continuity.
