NTSB Narrative Summary Released at Completion of Accident

On August 8, 2012, at 1230 mountain daylight time, an experimental amateur built Santana PA-18 Replica, N3AK, departed the runway surface after touchdown, and ground looped at the Ronan Airport (7S0), Ronan, Montana. The private pilot/owner operated the airplane under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. The pilot, the sole occupant, was not injured. The airplane sustained substantial damage to the left wing. Visual meteorological conditions prevailed for the local area flight, and no flight plan had been filed. According to the pilot, he had been in the pattern; he set up for landing on runway 34 and was encountering some convective turbulence. After the airplane touched down, it veered to the right; the next thing the pilot recalls was the airplane nose down in a ditch with the engine running. Upon inspection of the airplane, he noted that the tail wheel rudder spring connecting chains were disconnected.
