The helicopter sustained substantial damage when it impacted the terrain during a positioning flight. After spraying a field, the pilot landed, refueled, and completed a preflight inspection of the helicopter. The pilot then departed to spray another field. The pilot reported that during the agricultural flight there were no changes in the sound of the transmission or any other part of the helicopter. The helicopter impacted the terrain while in cruise flight and the pilot had no recollection of the accident. The inspection of the helicopter revealed that the transmission failed in-flight. Three worn and deformed lower pinion roller bearings from the lower planetary gear spider assembly were found loose in the transmission. The inner race for that pinion had missing rollers. It was spalled at both the upper row and lower row of its rollers. No spalling was found on the other five inner races from the lower spider assembly and no abnormal wear was found on rollers from the other pinions in the lower spider assembly.
Probable Cause: The total failure and seizure of the main rotor transmission while in cruise flight leading to the helicopter's impact with terrain.
