Incident Overview
A pilot flying a tailwheel airplane landed on a dry grass runway at a remote agricultural airstrip for the first time. The approach was to the south. Just before touchdown, the pilot observed a ground spray rig maneuvering toward the turf runway. The landing was uneventful, but during the landing roll, the pilot perceived that the spray rig was crossing the runway, believing a runway incursion was occurring. The pilot later stated, "[the spray rig] pulled out on me, not thinking it could be on the road that went around the end of the airstrip."
Sequence of Events
Due to his elevated seating position in the tailwheel airplane, the pilot incorrectly judged that the spray rig was on the runway. In response, he applied full power to execute a go-around. However, the turbine engine exhibited an acceleration lag, and the pilot realized he would not have enough time to perform a successful go-around. He then reduced power and attempted to stop the airplane before reaching the end of the available runway.
Damage and Impact
The airplane failed to stop and impacted a metal perimeter fence. The impact caused substantial damage to the fuselage, the right aileron, and the engine mount. The operator reported that there were no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation.
