## Discrepancy

DURING APPROACH WHILE HANDFLYING, THERE HAD TO BE SIGNIFICANT INPUT IN AILERON TO MAINTAIN LEVEL FLIGHT. FUEL INDICATIONS OF BOTH FUEL FLOW, QUANTITY, AND BALANCE SHOWED NORMAL. WHEN REFUELING TO 5,200, THE TOP OFF SYSTEM AUTOMATICALLY SHUT DOWN THE REFUELING SYSTEM, AND THE GAUGES INDICATED AN ALMOST 1100 POUND IMBALANCE WITH LEFT WING INDICATING 1470, CORRESPONDING WITH THE AILERON INPUT WE HAD TO MAKE. FUEL ON BOTH TANKS ARE TOPPED OFF.  REPLACED WIRE HARNESSES. OPS CHECK GOOD. IAW MM 28-41-00.
