## Discrepancy

DURING APPROACH, RT HYDRAULIC SYSTEM PRESSURE WAS LESSENED AND ABNORMAL PROCEDURE WAS PERFORMED. AIRCRAFT LANDED WITH LANDING GEAR DOORS DOWN. SYSTEM WAS CHECKED AND NO FAILURE WAS DETECTED, IT WAS PURGED AND 2 QUARTS WERE ADDED, QUANTITY AND PRESSURE TRANSMITTERS WERE CHECKED, ALL CORRECT. AS A PREVENTIVE ACTION, HYDRAULIC PUMP WAS REPLACED IAW MM 29-10-05,  TEST CORRECT. MLG DOORS WERE CHECKED IAW MM 32-12-00, ALL CORRECT.
