## Discrepancy

REMOVED THE RH FUEL TANK TO FACILITATE OTHER MAINTENANCE.  FOUND FUEL TANK BAFFLE SPOT WELDS BROKEN.  THE BAFFLE WAS ABLE TO MOVE AROUND FREELY INSIDE THE TANK.  THIS COULD CAUSE FALSE FUEL QUANTITY INDICATIONS DUE TO INTERFERENCE WITH THE TRANSMITTER FLOAT.  THIS IS LIKELY CAUSED BY INTENTIONALLY ALLOWING THE FUELING NOZZLE TO MAKE CONTACT WITH THE BAFFLE TO SUPPORT THE WEIGHT OF THE FUELING NOZZLE AND HOSE DURING REFULING.  MARKS ON THE LH FUEL TANK BAFFLE SUPPORT THIS THEORY.  THIS ISSUE WAS PREVIOUSLY ADDRESSED ON SDR 2003FA0000306, 2003FA0000291, 2003FA0000290, 2003FA0000290, 98ZZZX1650, 2003FA0000289, AND MENTIONED IN CESSNA SERVICE LETTER 63-54.
