## Discrepancy

INSPECTION FOUND THE RT MLG SHOCK STRUT LEAKING FLUID FROM TOP OF THE OUTER CYLINDER.  THE INNER AND OUTER CYLINDERS WERE REMOVED.  THE ORIFICE SUPPORT TUBE WAS REMOVED FROM THE OUTER CYLINDER AND FOUND TO BE CRACKED THROUGH.  THE INSIDE DIAMETER OF THE OUTER CYLINDER WAS INSPECTED AND NO DAMAGE WAS FOUND.  A NEW ORIFICE SUPPORT TUBE WAS INSTALLED ON THE EXISTING OUTER CYLINDER WHICH WAS REINSTALLED.  THE SHOCK STRUT WAS FULLY SERVICED AND LEAK AND OPERATIONAL CHECKS WERE GOOD.  THE ORIFICE SUPPORT TUBE WAS SENT TO BOEING FOR INVESTIGATION AND ANALYSIS.
