Narrative:

On the arrival descending through 18000 ft the xfer pump was discovered to be not pressurizing the left hydraulic system. It was noted that fluid in the right hydraulic system had decreased to 4 quarts (top of red arc). We did the QRH procedure for 'hydraulic quantity low or dropping' for the right side and extended the gear on the pressure from the left system through the xfer pump and landed without incident. The main gear doors were open for landing and had to be secured by maintenance once we cleared the runway. This resulted in an approximately 45 min delay on the taxiway. Once secured; we taxied to the gate without incident. Leaks were found in the right hydraulic system.

Title: MD80 FLT CREW EXPERIENCES FLUID LOSS FROM RIGHT HYDRAULIC SYSTEM AND AFTER COMPLYING WITH QRH PROCEDURES; LANDS SAFELY AT DESTINATION.

Narrative: ON THE ARR DSNDING THROUGH 18000 FT THE XFER PUMP WAS DISCOVERED TO BE NOT PRESSURIZING THE L HYD SYS. IT WAS NOTED THAT FLUID IN THE R HYD SYS HAD DECREASED TO 4 QUARTS (TOP OF RED ARC). WE DID THE QRH PROC FOR 'HYD QUANTITY LOW OR DROPPING' FOR THE R SIDE AND EXTENDED THE GEAR ON THE PRESSURE FROM THE L SYS THROUGH THE XFER PUMP AND LANDED WITHOUT INCIDENT. THE MAIN GEAR DOORS WERE OPEN FOR LNDG AND HAD TO BE SECURED BY MAINT ONCE WE CLRED THE RWY. THIS RESULTED IN AN APPROX 45 MIN DELAY ON THE TXWY. ONCE SECURED; WE TAXIED TO THE GATE WITHOUT INCIDENT. LEAKS WERE FOUND IN THE R HYD SYS.
