What was found
ON LANDING THE LT MAIN GEAR LOWER AND UPPER TORQUE LINKS SEPARATED AT THE CONNECTING BOLT. I FEEL THAT THE COTTER PIN CAME OUT, WHICH ALLOWED THE NUT TO UNSCREW FROM THE BOLT, LETTING THE BOLT TO FALL OUT OF THE TORQUE LINKS. I WOULD RECOMMEND CLOSER INSPECTION BY MAINTENANCE PERSONNEL AND PILOTS ON PREFLIGHTS. PLUS REPLACEMENT OF COTTER PINS AT ONE YEAR INTERVALS.
