Incident Overview
During the final approach to land, a pilot observed an individual on a small lawn-type tractor positioned well clear on the left side of the runway. The pilot proceeded with the landing.
Sequence of Events
Just after touchdown, while the pilot was lowering the nose of the aircraft, he observed the tractor pass under the left wing. The pilot reported that he felt no impact during the event. After turning off the runway, he inspected the aircraft and noted that the leading edge of the wing was dented.
Aftermath
The pilot notified the airport manager, who subsequently inspected the runway. The operator of the tractor was found lying on the left side of the runway. He had sustained serious head injuries and was transported to a hospital for medical treatment.
