## Discrepancy

PILOT NOTICED HYD FLUID LEAKING ON GROUND AND LT SIDE OF ACFT.  MECHANIC ARRIVED AND SERVICED NR2 HYD SYS.  PERFORMED GROUND RUN AND FOUND FLUID SQUIRTING FROM B-NUT/ T-FITTING ON THE RETURN LINE, COMING FROM THE FILTER MANIFOLD.  DISCOVERED B-NUT WAS NOT EVEN FINGER TIGHT.  TIGHTENED B-NUT AND ALL SURROUNDING FITTINGS, RESERVICED HYD RESERVOIR.  PERFORMED GROUND RUN FOR 5 MINUTES WHILE PILOT PERFORMED A HYD SYS CHECK WHICH CHECKED GOOD.  AFTER SHUTDOWN MECHANIC CHECKED FOR LEAKS- NONE FOUND.  PERFORMED MX HOVER, THEN FLIGHT.  ALL CHECKS WERE NORMAL AND NO FURTHER LEAKS WERE NOTICED.  ACFT RETURNED TO SERVICE.
