The NTSB's narrative final · quoted from the NTSB record

According to the pilot in the tailwheel-equipped airplane, he landed on tundra that had an uphill slope. Before touchdown, the pilot shut off the engine "in case of a nose over event." He reported that, after the landing roll, when the airplane was completely stopped on level ground, a tailwind gust lifted the tail. The airplane balanced on the nose for about 10 seconds, a second gust pushed the airplane over, and it came to rest inverted. The airplane sustained substantial damage to the rudder. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
