A JETSTREAM 32 ON APCH AT 2500 FT DECLARED AN EMER DUE TO LOSS OF ALL HYD PRESSURE AND QUANTITY CAUSED BY THE FAILURE OF A LINE AND FITTING IN THE AUX HYD SYS.

Narrative

ON APCH; WHEN LOWERING GEAR AND SELECTING FLAPS; A STRANGE NOISE WAS HEARD. SCANNING THE INSTS; IT WAS DISCOVERED THE HYD PUMP OUTPUTS (2) WERE ZERO. WE WENT MISSED APCH; ADVISED THE TWR THAT WE NEEDED TIME TO INVESTIGATE A POSSIBLE PROB. TWR INITIALLY ADVISED US TO HOLD IN THE TFC PATTERN; THEN LATER CLRED US TO MANEUVER AT OUR DISCRETION. BOTH MYSELF AND MY FO REVIEWED OUR CHKLISTS; SEEING IF WE COULD FIGURE OUT ANY PROB. NO CHKLIST ADDRESSED OUR PROB. WE CALLED OUR OPS DEPT; WHO CALLED OUR MAINT BASE IN ST LOUIS. HE DESCRIBED OUR SIT. MAINT HAD NO SUGGESTIONS OTHER THAN LNDG AT FT WAYNE. TWR CALLED AND ASKED FOR AN UPDATE. WE TOLD THEM WE'D RATHER NOT DESCRIBE THE SIT UNTIL WE HAD FULLY ASSESSED IT. WE CALLED OPS TO RECEIVE LNDG DATA FOR FLAPS WITHOUT FULL FLAP SETTINGS. THEY COULD NOT GET IT FOR US; AND OUR PERFORMANCE DATA DID NOT INCLUDE IT. WE THEN CALLED TWR; LET THEM KNOW THE SIT; REQUESTED VECTORS TO FINAL; AND EQUIP (CRASH/FIRE) ON ALERT. TWR ADVISED US CRASH/FIRE WAS ALREADY STANDING BY; AND WE RECEIVED A LNDG CLRNC. WE LANDED WITH NO FURTHER INCIDENT. ON FINAL; OUR LNDG FLAPS DID LOWER WITH HYD PRESSURE. POSTFLT INSPECTIONS REVEALED HYD FLUID STREAMING FROM AN UNKNOWN SOURCE UNDER THE ACFT. CRASH/FIRE RESCUE DOES A VALUABLE SVC; HOWEVER; THEY NEED BETTER COORD WITH AIRLINE OPS TO EVALUATE THE SIT. THEY MUST UNDERSTAND A PLT'S FIRST RESPONSIBILITY IS AVIATE; THEN COMMUNICATE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS A JETSTREAM 32 AND THE CAUSE OF THE COMPLETE LOSS OF HYD FLUID WAS THE FAILURE OF A LINE AND FITTING IN THE AUX HYD SYS. THE RPTR SAID THE LINE WAS LOCATED NEAR THE RESERVOIR AND WHEN THE LINE FAILED IT ALLOWED THE MAIN AND AUX SYS TO BE DRAINED.
