## Discrepancy

FUEL FILTER ASSY DEVELOPED A LEAK.  WAS CHANGED OUT THEN THE SERVICEABLE ONE INSTALLED.  OPS CHECK GOOD FOR MAINTENANCE, BUT THE NEXT DAY ON PREFLIGHT INSPECTION BY THE PILOT THE FILTER "BYPASS" WARNING LIGHT BUTTON ON THE ASSY WOULD NOT OPERATE CORRECTLY.  PART WAS CHANGED AGAIN AND IS NOW OPERATING CORRECTLY AND NOT LEAKING.
