The aircraft came to rest 200 feet from the edge of the runway, with a collapsed right main gear. Both the pilot and passenger were unharmed. No damage to the airport property and structures were noted.
Photographs taken at scene indicate significant structural damage of right hand wing. Right hand wing center section skin buckled at landing gear box structure. Upper wing wrinkling extends through the outer wing.
