The pilot was on a fire retardant application run. He successfully dropped half his load on the fire and went around for another run. On the second pass, the aircraft encountered a strong downdraft as it neared the release point and the pilot recovered at a low altitude. During this process, the left outer wing collided with the top of a juniper tree. The pilot returned to Elko and landed. The most outboard 4 feet of the wing leading edge was crushed aft with rib damage.
