## Discrepancy

ON TAKEOFF OUT OF MSP, HYD PUMP WOULD NOT WORK IN OVERRIDE MODE.  AFTER GOING THROUGH QRH IT OPERATED AGAIN.  ON LANDING IN MSP, OVERRIDE MODE WOULD NOT WORK UNTIL JUST REACHING THE GATE.  MAINTENANCE REPLACED HYD PUMP PER SF340 AMM 29-10-10.  PERFORMED FUNCTIONAL CHECKS OF HYD PUMP.  OPS AND LEAK CHECKS GOOD.  SERVICED HYD.
