## Discrepancy

ACFT WAS STARTED, ROTOR WAS WOUND UP.  HYD PRESSURE CAME ON-LINE FOR NR 1 SYS, NR 2 SYS GAVE ERRATIC INDICATION AND THEN WENT TO ZERO PRESSURE.  ACFT WAS SHUTDOWN.  NR 2 HYD PUMP WAS REMOVED FROM MAIN GEARBOX. DRIVE SHAFT SPLINES ON PUMP SIDE WERE FOUND STRIPPED OUT.  PUMP WAS REPLACED AND THE ACFT WAS GROUND RUN SERVICEABLE.
