## Discrepancy

RIGHT MAIN TANK FUEL QUANTITY INDICATION APPEARS TO BE ERRONEOUS. JUST PRIOR TO CENTER FUEL EMPTYING RIGHT MAIN QTY JUMPED TO 9140 LBS, WHERE IT STABILIZED FOR A FEW MINUTES. IT THEN BEGUN COUNTING DOWN NORMALLY. HOWEVER; THERE IS APPROXIMATELY A 1000 LB SPLIT BETWEEN LEFT AND RIGHT TANKS. ALL FUEL FLOWS/FUEL USED INDICATIONS ARE NORMAL. GROUNDED - YES.
