## Discrepancy

(CAN) INTERMITTENT FUEL QTY INDICATION.  IN FLIGHT AND ON GROUND FUEL QTY INDICATOR ERRATIC OR OVER READ WITH NO REPORTED FAULTS LOGGED ON THE REPEAT INDICATOR WHEN INSPECTED BY MX PERSONNEL.  WE RECENTLY FACED AN INTERMITTENT FUEL INDICATION SNAG. PILOTS REPORT AN INTERMITTENT FUEL IMBALANCE. (SYS OVER READ THE REAL QUANTITY BY UP TO 700 LBS. SYS SHOW 5600 LBS BUT IN FACT FUEL ON BOARD IS 4900 LBS.  SINCE THIS IS AN INTERMMITENT SNAG AND THE SYS DOES NOT LOG ANY FAULTS THE MFG RECOMMENDED TO PERFORM A SELF-TEST OF THE FUEL QTY COMPUTER AND IF NO FAULT IS DISPLAY PROCEED WITH NORMAL OPERATION AND MONITOR THE SITUATION (IAW SL DH8-400-SL-28-001)  THE FUEL DIP STICK COULD ALSO BE USED TO CONFIRM THE FUEL QUANTITY WHEN PILOT SUSPECTS A POSSIBLE UNBALANCE.  SINCE THE SYS DOES NOT FLAG A POSSIBLE SNAG OF FUEL QTY READ OUT, THIS MAY BE A POTENTIAL OF REAL FUEL UNBALANCE.
