Read the full NTSB narrative
A witness stated that the airplane 'flared smoothly and touched down with what appeared to be no side load.' As the aircraft settled onto the runway surface, the right main gear collapsed, and the aircraft subsequently skidded off the right side of the runway. During examination of the right main landing gear, it was discovered that the gear pivot assembly was fractured adjacent to the spline. It has not been determined as to whether the fracture occurred during gear retraction, extension, or upon contact with the runway. According to maintenance records, Cessna Service Bulletin, SE390.1, April 20, 1990, was applicable to this aircraft and was complied with. The Service Bulletin's purpose was to inspect main landing gear pivot assemblies for cracks in the spline area. The pivot assembly that failed, P/N 2441100-9, had a total time of 1,611.8 hours. Visual inspection of the fractured surface showed evidence of overload, however a small area on the outer portion of the surface had several small cracks bordering the edge.
