The pilot was landing at a private airport near Gustavus, Alaska, that is used to support fish cannery operations.
A road runs parallel to the runway with multiple intersections where motor vehicles cross the runway.
The airport is equipped with a pre-landing alert system to warn ground personnel that an aircraft is approaching. The pilot keys the aircraft radio’s push to talk switch multiple times, which activates a series of flashing lights and horns.
The pilot reported that before landing he activated the pre-landing alert system, and proceeded to land to the north.
After touchdown, but during the landing rollout, at approximately 30 miles per hour, a truck entered the runway and struck the left side of the Cessna 206. The airplane sustained substantial damage to the left horizontal stabilizer and elevator.
In the recommendation section of the NTSB Accident/Incident Reporting Form 6120.1, the pilot stated that the accident may have been avoided if the cannery provided initial and recurrent training for all employees on runway safety and aircraft operations.
In addition, the pilot recommended better signage be incorporated at all runway intersection crossings, and brush and trees be cleared from the vicinity of the runway to increase visibility.
The NTSB determined the probable cause as the motor vehicles operators’ lack of attention, and improper decision to cross the runway with the runway alert system active, resulting in a collision with the airplane.
