## Discrepancy

WHEN FUELING THE AIRCRAFT, FUEL TOTAL IS NOT ACCURATE. CONSISTENTLY SHOWS 200-300# LESS THAN WHAT IS REALLY LOADED. INACCURATE TOTAL WILL SHOW UNTIL 5 -10 MINUTES AFTER TAKEOFF. FURTHER, THE FUSELAGE TANK WILL NEVER FULLY EMPTY; WILL NOT DRAIN BELOW 80# OF FUEL. REPLACED FUSELAGE FUEL PROBE IAW LEARJET 75 AMM 28-40-05. REPLACED FUSELAGE CELL ASSEMBLY IAW AMM 28-10-05. REPLACED FUSELAGE REFUEL MANIFOLD ASSEMBLY IAW AMM 28-20-13. OPS AND LEAK CHECK GOOD.
