During the approach with a right quartering headwind, he maintained a normal approach speed and landed the airplane utilizing a 3-point landing technique. During the landing rollout, the airplane began to drift to the right and he applied left rudder to correct. As the airplane approached the edge of the paved surface he applied brake pressure. Subsequently, the airplane nosed over and came to rest inverted which resulted in substantial damage to the rudder. The pilot reported no mechanical malfunctions or abnormalities that would have precluded normal operation. The pilot reported the winds at the airport as 340 degrees and 5 knots and a nearby weather station recorded the winds around the time of the accident as 290 degrees at 5 knots. ## Factual narrative According to the pilot, this was the fifth landing in the tailwheel equipped airplane that morning, with the other four landings being at a nearby airport.
