Narrative

ON JUL/XA/06 I FILED RPT BECAUSE I THOUGHT I HAD TAKEN AN ACFT WITH A QUESTIONABLE DISPATCH AND I WANTED THE COMPANY TO VERIFY THAT WHAT I THOUGHT WAS IN FACT CORRECT. LATER IN JULY; I ENCOUNTERED THE VERY SAME DISPATCH PROB. I HAD NOT HEARD FROM THE COMPANY AS TO WHETHER MY INTERP WAS CORRECT OR NOT. HOWEVER; I WAS LOOKING AT IDENTICAL MEL'S. CTR TANK SYS 28-21-02 AND AUTOMATIC FUEL FEED SYS 28-20-01. BOTH MEL'S AS STAND ALONE MEL'S ARE FINE BUT MY CONTENTION OR QUESTION WAS BASED UPON WHAT IS WRITTEN AND THE INTERP THEREOF IS WHAT WE WERE QUESTIONING. THERE IS NO PROB WHATSOEVER WITH THE OPERATIONAL PROC AND WE CAN APPLY IT. THE CONCURRENT MEL OF 28-20-01 'AUTOMATIC FUEL FEED.' IN THE REMARKS SECTION OF THE MEL IT STATES THAT: (0) MAY BE INOP PROVIDED OPERATIONAL PROCS BELOW ARE FOLLOWED. THE OPERATIONAL PROC OF TURNING BOTH PUMPS ON CANNOT BE FOLLOWED ON THIS MEL BECAUSE OF THE PREVIOUS MEL WHICH HAS TOLD YOU TO TURN OFF THE AFFECTED CTR TANK PUMP. IN OUR CASE IT WAS PUMP #1 COULD NOT BE TURNED BACK ON. THIS IS A DIRECT CONTRADICTION/CONFLICT AND NO LONGER ALLOWS YOU TO COMPLY WITH THE MEL 28-20-01 BUT MAINT CONTENDED THAT THE LOGIC MAKES SENSE AND THERE IS NO LEGALITY ISSUES AS FAR AS THEY WERE CONCERNED. SINCE I HAD A QUESTION ON THIS RELEASE; I CALLED MAINT AND WE SET UP A CONFERENCE CALL BTWN DISPATCH; MAINT CTL; CHIEF PLT'S OFFICE AND MYSELF. WE ALL CAME TO THE CONCLUSION THAT THE 2 MEL'S WERE WORDED POORLY AND THAT THE INTENTION AND LOGIC OF THE OPERATIONAL PROC MADE THE ACFT AIRWORTHY. THE CHIEF PLT ON DUTY SUGGESTED THAT IF WE DISPATCHED THE ACFT TO A LOCATION THAT WE COULD MAKE WITHOUT ANY CTR TANK FUEL WE WOULD THEN BE LEGAL TO DISPATCH AND THE OPERATIONAL PROC WOULD NOT BE AFFECTED BECAUSE WE WERE NOT PLANNING ON USING ANY FUEL FROM THE CTR TANK. AT XA00 THIS SOUNDED LOGICAL SO WE WENT WITH HIS PLAN AND DISPATCH PROCEEDED TO DISPATCH US TO ZZZ1 WHICH WE COULD MAKE WITHOUT CTR TANK FUEL.
