Analysis

The plt was loading xmas trees from a farm to a truck. He had just released a load and was en route back to the pickup area when the empty long-line sling contacted treetops. The sling rebounded into the tail rotor & damaged the gear box which resulted in loss of control. The plt initiated an autorotative landing, but the helicopter touched down hard.
