The pilot reported that the landing gear system had undergone recent maintenance as part of the airplane's last annual inspection, which was completed in May 2006.
Post-Incident Examination
Following the incident, an FAA inspector examined the airplane. The inspection revealed that the pivot bolt on the right main landing gear down-lock bell crank fulcrum had failed. The reason for the failure could not be determined.
Summary
This incident involved the collapse of the right main landing gear after touchdown despite the gear appearing to be locked. The failure of a specific component was identified, but no definitive cause for the failure was established.
