What happened
During a Part 135 cargo flight, the pilot passed the outer marker and deployed the landing gear, noting that the three green lights indicated normal operation. Upon touchdown at the runway's fixed distance markers, the pilot held the nose off the ground. During this phase, the aircraft felt as though the right main gear was locked and the aircraft was riding the brakes. After the pilot released pressure on the rudder, the aircraft drifted to the right. The pilot attempted to lower the nose wheel to regain steering control, but the drift continued. Consequently, the left propeller struck the ground and the nose landing gear collapsed.
The investigation
An examination of the Cessna (type not specified in source) revealed that the left main landing gear had collapsed during the landing sequence. Further inspection identified that the left main landing gear torque link assembly, part number 5141005-7 (scissors assembly), had failed. Records indicated that maintenance had been performed on both the main and nose landing gear scissors assemblies 22.1 hours before the accident, which involved the removal and replacement of worn bushings.
