## Discrepancy

THE CREW NOTED ZERO HYDRAULIC PRESSURE FOLLOWED BY ERRATIC PRESSURE INDICATIONS ON THE HYDRAULIC PRESSURE GAUGE.  THERE WAS NO INDICATION OF HYDRAULIC SYSTEM FAILURE DUE TO THE LACK OF THE ANNUNCIATOR LIGHT INDICATIONS.  AFTER LOWERING THE FLAPS AND GEAR THE PRESSURE GAUGE STABILIZED AT 1700 PSI AND THE CREW DIVERTED TO FLL.  UPON SUCCESSFUL LANDING AT FLL THE CREW TAXIED TO BOMBARDIER.  BOMBARDIER TROUBLESHOT AND FOUND PRESSURE TRANSDUCER CORRODED.  REMOVED AND REPLACED PRESSURE TRANSDUCER.
