## Discrepancy

ON APPROACH, ATTEMPTED NORMAL GEAR EXTENSION BUT HYDRAULIC PRESSURE WAS TO LOW TO EXTEND THE GEAR. EXTENDED GEAR USING EMERGENCY GEAR PROCEDURE AND LANDED WITH NO PROBLEM. FOUND RT ENGINE DRIVEN HYDRAULIC PUMP PRESSURE LINE LEAKING. REMOVED AND REPLACED HOSE ASSEMBLY. LEAK AND OPS CHECKS GOOD.
