The airplane bounced during the touchdown, and the airplane began a hard porpoise down the runway. The nose landing gear wheel cracked and separated from the airplane, and the airplane nosed over. The airplane sustained substantial damage to the vertical stabilizer, the rudder, and the left wing strut. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that he was practicing takeoffs and landings to the asphalt runway.
