## Discrepancy

RETAINING BOLT FOR THE RIGHT MAIN LANDING GEAR TRAILING LINK ARM HINGE PIN SHEARED ON THE GROUND. BOLT IS A AN4-27. THE SHEARED BOLT ALLOWED THE PIN TO ROTATE WHICH MOVED THE PROXIMITY SENSOR TARGET AND CAUSED A RH WOW FAULT CASS  MESSAGE TO ANNUNCIATE ON THE MFD. NO OTHER DAMAGE OR ADDITIONAL FINDING WERE NOTED DURING THE COMPONENT INSPECTIONS AND REPLACEMENT OF THE BOLT. THE BOLT WAS REPLACED WITH NEW DURING ROUTINE INSPECTION  265 HOURS AND 268 LANDINGS PRIOR.
