## Discrepancy

DURING FLIGHT ON FINAL APPROACH, NOTICED A MASSIVE DROP IN FUEL QUANTITY. FUEL CHECK INITIATED UPON DEPARTURE AT 790LBS. MAIN FUEL, ON FINAL APPROACH INTO STAGEFIELD MAIN FUEL INDICATED 234LBS. EQUALING 556LBS. USAGE IN 15 MINUTES. NO FUMES OR VISIBLE LEAKS WERE DETECTED. T/P MOC DETECTED FUEL INDICATION IS UNRELIABLE. AFTER REFUEL THE FUEL INDICATION SHOWED 660LBS. FUEL FLUCTUATED FROM 660 TO 1150LBS. THEN REMAINED STEADY DURING FLIGHT. SUSPECT WHEN FUEL IS BELOW A CERTAIN LEVEL IN THE TANK IT BECOMES UNRELIABLE.
