Probable cause

The pilot's selection of an unsuitable landing area. Contributing factors were the tall vegetation on the sides of the airstrip and the short and confined landing area.

Analysis

The 2,670-hour commercial pilot lost control of the turbine-powered aerial application airplane while landing on a remote dirt airstrip to replenish the hopper. The pilot reported that while flaring the airplane during a 3-point landing, the upwind wing (low wing) became entangled in the tall vegetation surrounding the airstrip resulting in a loss of directional control. The airplane "cart-wheeled" and came to rest in the upright position. The pilot was able to exit the airplane unassisted. The airplane's aft fuselage sustained structural damage. When asked how this accident could have been prevented, the pilot responded that a better choice of airstrip could have been made to prevent the mishap.
