Event Description
During the landing rollout following a normal approach, the pilot reported hearing a "metallic clank" sound. Immediately afterward, the right main wheel broke, and the airplane veered off the runway into rough terrain and high vegetation.
Post-Accident Examination
Examination of the runway revealed black smudge marks consistent with rubber transfer from the airplane's right main landing gear tire. Broken right wheel assembly components were found at the accident site. The airplane was recovered and the right main landing gear wheel assembly was examined. Upon disassembly, the inboard hub section was found broken at the inboard flange cap screws.
The pilot reported that he believed the hub was likely an original component, and its total time in service was 3,045.2 hours.
Maintenance Background
The Cessna T210 series service manual indicates that the landing gear main wheels should be removed and disassembled, and the components inspected every 50 hours. The airplane's maintenance records indicated that it had been four years since new tires had been installed. There were no other maintenance entries to indicate that the wheel had been disassembled for inspection. An annual inspection was completed nine months and 44 hours prior to the accident.
