Shortly after touchdown the inner tube of the right main tire failed, and the airplane began drifting to the right. When the steel rim of the right main wheel made contact with the asphalt, full left rudder and brake were not sufficient to keep the airplane from departing the right side of the runway. As the ground loop progressed, the left wing and left elevator contacted the ground. Both the left wing and the left elevator sustained structural damage. ## Factual narrative The pilot reported that he was performing a wheel landing with his tailwheel-equipped airplane.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
