ANC99LA020

The certificated airline transport pilot, with five passengers, was taxiing to the operator's facility at the conclusion of an on-demand air taxi flight. The taxiway connects the main airport complex with outlying operator's facilities around the perimeter of a lake. The taxiway had private airplane tie-down lots located along its length. A snowplow equipped pickup truck was removing snow from a private airplane tie-down spot, located alongside the taxiway. The truck, operated by the owner of the tie-down spot, was equipped with a metal lumber rack in the bed of the truck. While positioning the truck, the owner backed across the taxiway, into the path of the accident airplane. A portion of the lumber rack struck the outboard end of the left wing of the airplane, damaging 3 feet of the leading edge, including several wing ribs. The airport permits limited vehicular traffic on the taxiway, primarily service vehicles and aircraft owners. It is not open for use by the general public. There are two signs located about 50 feet from the point of collision. One sign that faces south reads, 'Caution Aircraft Operation Area - Yield to all Aircraft.' A second sign that faces north reads, 'Aircraft Only - No Vehicles or Pedestrians on Taxiway.'
