What happened
The aircraft's main landing gear collapsed during the initial phase of touchdown. Following the failure of the right main gear, the aircraft veered sharply to the right side of the runway. It eventually came to rest approximately 600 feet beyond the runway threshold and 90 feet northwest of the runway edge.
The investigation
An FAA inspector examined the wreckage and determined that an adjusting screw (part number 0841113-1) located on the retraction linkage had failed. This failure caused the right main gear to retract unexpectedly, which in turn sheared a bolt (part number NAS 46404-26) on the bellcrank assembly.
Findings
A Cessna representative noted that such a failure could result from general wear or misrigging of the components. The company that owned and operated the aircraft ceased flight operations approximately six months after this accident occurred.
