## Discrepancy

FLT NR 525 - IAH - THE 'B' SYSTEM HYDRAULIC QUANTITY GAUGE INDICATED ZERO AND WAS ACCOMPANIED BY ILLUMINATION OF THE NR 2 'B' SYSTEM PUMP LIGHT WHILE IN FLIGHT.  ABNORMAL PROCEDURES WERE COMPLIED WITH AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE NR 1 AND NR 2 'B' SYSTEM PUMPS DUE TO LEAKAGE.
