Analysis

A Cessna 310 right main gear collapsed while taxiing off the runway at the lgb. The pilot reported that he felt a vibration during the initial takeoff roll and opted to abort the takeoff. As the pilot exited the runway the right main gear collapsed. Investigation revealed that the airplane had been returned to service following an annual inspection and landing gear maintenace on March 03, 1989. Aircraftsman, a fixed base operator at the Long Beach airport had replaced all bushings and spacers in the main gear torque links. It was found that the torque link center attach bolt washer was under size, allowing the upper torque link to pull free from the lower torque link.
