WHILE TAXIING, THE PILOT (PIC) NOTICED A GRAVEL TRUCK PARKED IN THE VICINITY OF THE TAXIWAY. SHORTLY BEFORE REACHING THE GRAVEL TRUCK, HIS ATTENTION WAS DIVERTED TO A TRACTOR DOING WORK IN THE RUN-UP AREA FOR RUNWAY 31 (TO WHICH HE WAS TAXIING). WHEN HE RETURNED HIS ATTENTION MORE CLOSELY TO HIS TAXIING, HE SAW HE WAS TOO CLOSE TO THE GRAVEL TRUCK AND APPLIED BRAKES, BUT THE RIGHT WING OF THE AIRPLANE STRUCK THE GRAVEL TRUCK. THE GRAVEL TRUCK WAS NOT MOVING AT THE TIME.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

INADEQUATE VISUAL LOOKOUT BY THE PILOT DUE TO HIS DIVERTED ATTENTION. THE VEHICLES (TRACTOR & TRUCK) WERE CONSIDERED TO BE RELATED FACTORS.
