Narrative:
Level 1 'fuel qty 2 disag' fault after refueling. Maintenance worked the problem and it was evident that the fault at least in part was that the #2 tank; 10;000 pounds float was at fault. This item is not deferrable as per the MEL; the other floats are. Maintenance control came up with MEL 28-01-01-02; #2 'main tank fuel qty indicators inoperative'. This MEL involved disconnecting various cannon plugs which completely disabled the #2 tank indicating system; including the potentially defective 10;000 pounds float; i.e.; no more peeps out of it. This procedure was essentially just sweeping trash under the rug to make the problem go away instead of addressing it directly.
