Rockwell International Commander S2R, VH-DQA, 3km W Elmore VIC, 17 October 1989

The pilot was conducting spraying operations in a large wheat paddock. The aircraft was being flown about two metres above the crop and the pilot intended to pass to the right of a large tree near the end of the particular swath run. The aircraft suddenly swung violently to the left as the wheels entered the crop. By the time the pilot managed to pull the aircraft clear, it was heading for the tree. While attempting to manoeuvre the aircraft, the pilot was unable to prevent it from striking the ground.
