Analysis

The helicopter collided uncontrolled with the terrain during external load operation. A 100 ft steel cable was attached to the cargo hook on the helicopter and a nylon sling was attached to the cable so a snowcat could be pulled out of a mud area. The plt stated that as he began to pull from the rear of the snowcat, the lateral CG was exceeded and the helicopter impacted shallow water on it's right side.
