## Discrepancy

UPON LANDING, THE "FUEL" CAUTION ILLUMINATED WITH 51 GALLONS INDICATED. THE MECHANIC ARRIVED AND DETERMINED THAT THE LOW FUEL FLOAT SWITCH WAS THE SOURCE OF THE FAILURE. THIS AIRCRAFT REMAINS OOS AT THIS TIME TO REPLACE THIS SWITCH AS WELL AS PERFORM OTHER SCHEDULED MAINTENANCE TASKS.
