A B727 WITH A RPTED R WING FUEL DUMP VALVE LEAKING WAS SIGNED OFF WITHOUT PRESSURIZING THE FUEL MANIFOLD.

Narrative

ON PREFLT FE FOUND THE R DUMP NOZZLE LEAKING FUEL WHILE THE FUEL TRUCK WAS FUELING THE AIRPLANE. THE DISCREPANCY WAS ENTERED INTO LOG AND MAINT CAME AND SIGNED OFF THE DISCREPANCY WITHOUT PRESSURIZING THE DUMP MANIFOLD. WE WERE NOT SATISFIED WITH THE SIGN OFF AND AFTER TALKING WITH THE MAINT SUPVR; NOTHING ELSE WAS GOING TO BE DONE. WE INSISTED THAT THE DUMP MANIFOLD BE REPRESSURIZED TO SHOW THE LEAK. A TECHNICIAN WAS SENT OUT AND THAT IS WHAT WE DID. THE R DUMP NOZZLE LEAKED IN THE CLOSED POS WITH THE DUMP MANIFOLD PRESSURIZED. THE ACFT WAS TAKEN OTS. MORE INFO; AS I WAS PRINTING PART ONE OF THIS RPT I TURNED FROM THE COMPUTER AND WAS AMAZED TO FIND ANOTHER CREW STANDING BY TO TAKE THE SAME ACFT OUT. I WAS TOLD BY THE WHITE SHIRT MAINT TECHNICIAN THAT THE PLANE WAS OTS. THE CREW WAS GIVEN THE ACFT AS IF NOTHING WAS WRONG AND MAINT WAS SENDING THE PLANE OUT. I INFORMED THE OUTBOUND CAPT OF THE DISCREPANCY AND WHAT HAD TRANSPIRED. ADDITIONALLY; UPON BOARDING OUR REPLACEMENT ACFT A NON REVENUE FO WHO WAS BOARDING THE SAME ACFT LATE HAD ASKED THE MAINT PERSONNEL ON THE BRIDGE WHAT WAS WRONG AND SAID THE RESPONSE WAS NOTHING AS FAR AS WE ARE CONCERNED. ON TAXI OUT IN OUR REPLACEMENT ACFT I NOTICED MAINT WAS APPARENTLY CHANGING THE R DUMP NOZZLE VALVE.
