The pilot of the tailwheel equipped airplane reported that he was performing a wheel landing on a turf surface runway. He recalled that he was too aggressive and too early moving the stick forward during the touchdown and landing roll. The airplane's tail ascended, the nose pitched down and the propeller stuck the ground. The airplane nosed over and came to rest inverted. The airplane sustained substantial damage to the vertical stabilizer and the rudder. Per the National Transportation Safety Board Pilot Aircraft Accident Report, the pilot reported that the accident could have been prevented, "by not being so early moving the stick forward in a taildragger during a wheel landing." The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
