## Discrepancy

(CAN) O-RING ON ACCUMULATOR SPLIT CAUSING HYDRAULIC FLUID LOSS. SUBSEQUENTLY THE PILOT TURNED THE #2 HYDRAULIC SYSTEM OFF AND LANDED THE AIRCRAFT. FURTHER INVESTIGATION REVEALED THAT THE #2 HYDRAULIC RESERVOIR WAS COMPLETELY DRY. THE ACCUMULTOR WAS DISASSEMBLED AND INSPECTED REVEALING THAT THE PISTON O-RING HAD SPLIT THE O-RING WAS REVEALED AND THE REASSEMBLED ACCUMULATOR RETURNED TO SERVICE.
