Narrative:The pilot stated that he had just landed at a remote site after emptying his bucket. As he unloaded the main rotor, it contacted a berm on the right side of the helicopter. This resulted in a sudden stoppage and damage to the transmission.
Probable Cause: the pilot's misjudgement of rotor clearance from the terrain. The proximity of the berm was a related factor.
