## Discrepancy

(CAN) AFTER A PILOT REPORTING THE RT MAIN GEAR OLEO WAS LOW, MAINTENANCE ATTEMPTED TO INFLATE THE OLEO WITH NITROGEN. THE NITROGEN IMMEDIATELY STARTED TO LEAK FROM A LARGE CRACK AROUND THE UPPER TORQUE KNEEBOSS ON THE BRACE ASSEMBLY. THE CRACK WAS APPROXIMATELY 6 INCHES IN LENGTH STARTING AT THE BOTTOM OF THE BRACE ASSEMBLY, GOING UP THE RADIUS ON THE LT SIDE OF THE BOSS AND TURNING AND CROSSING OVER THE TOP OF THE BOSS. THIS GEAR HAD 277 CYCLES SINCE INSPECTION.
