## Discrepancy

AFTER TAKEOFF, THE NR 2 ENGINE HYD PUMP CAUTION LIGHT ILLUMINATED AND THE NR 2 HYD SYS LOST PRESSURE AND ALL ASSOCIATED EQUIPMENT DID NOT WORK.  THE CREW RETURNED TO FIELD.  THE GROUND CREW REPLACED THE  NR 2 ENGINE DRIVEN HYD PUMP.  A SATISFACTORY OPERATIONAL CHECK WAS CONDUCTED AS WELL AS A LEAK CHECK WHICH PRODUCED NOTHING OF CONCERN.  THE ACFT WAS RETURNED TO SERVICE.
