During the landing roll, he applied the brakes too aggressively and the airplane nosed over. The airplane sustained substantial damage to the right-wing strut, the rudder and vertical stabilizer. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative According to the pilot in the tailwheel-equipped airplane, he was practicing touch-and-go takeoffs and landings on the turf adjacent to the paved runway.
