While taxiing from landing following a post-annual inspection flight, the right main landing gear collapsed. Maintenance records indicated both main landing gear push-pull tubes had been removed when the gear was rigged. The service manual requires the drive tubes --- not the push-pull tubes --- be disconnected. The left push-pull appeared to have been installed upside down and had not been properly aligned. Aircraft load was transmitted to the center pivot on the main landing gear bellcrank, causing it to fail. NTSB's Materials Laboratory said there was a "ductile overstress fracture in direct shear," causing instantaneous overload of the bolt.
Probable Cause: total failure of the main landing gear due to improper installation of the push-pull tubes by maintenance personnel, and their failure to follow proper procedures/directives.
