According to a witness, the pilot executed a normal landing. During the landing roll, the right main landing gear impacted a culvert. The airplane veered to the right and came to rest inverted, resulting in substantial damage to the fuselage, wings, and vertical stabilizer. The pilot reported there were no preexisting mechanical anomalies with the airplane.
