The left main landing gear collapsed during a precautionary landing. The pilot reported that after takeoff, he suspected a landing gear malfunction and returned to the airport. He made a gear up low approach to the airport. Maintenance personnel told him that the left gear was still extended. The pilot cycled the gear down and observed the landing gear lights were illuminated, indicating the gear was down and locked. The pilot made a soft field landing and let the airplane roll to the end of the runway. As he started to turn left, the left main gear collapsed. Post accident examination of the landing gear assembly revealed that the roll pin (part number NAS561P4-28) that retains the attaching shaft to the trunnion assembly had fractured and failed. This allowed the landing gear attaching shaft to shift from its installed position, resulting in the trunnion assembly separating from the landing gear support structure.
