## Discrepancy

(CAN) DURING COMPLETE REMOVAL AND NDT OF ALL LANDING GEAR PARTS BOTH LT & RT MAIN GEAR PISTON AND AXLE ASSEMBLIES (P/N S 5041000-77 & 5041000-76 RESPECTIVELY) WERE FOUND CRACKED AT THE SMALLER OF THE TWO TORQUE LINK ATTACH LUGS.THE RT WAS REPLACED WITH A USED SERVICEABLE UNIT, HOWEVER 10 USED LT UNITS WERE TESTED AND FAILED PRIOR TO FINDING A SERVICEABLE USED ONE TO INSTALL.  WE FEEL FINDING A GOOD USED RT UNIT ON THE FIRST TRY WAS JUST A STROKE OF LUCK.
