## Discrepancy

PILOT REPORTED FUEL ODOR IN COCKPIT/CABIN. I INSPECTED ALL FUEL LINES AND FITTINGS IN ENGINE COMPARTMENT NO DEFECTS NOTED. INSPECTED FUEL SUMPS AND CAVITY DRAINS NO DEFECTS NOTED. INSPECTED AFT COMPARTMENT ( BAGGAGE AREA SIDE WALL PANEL ) AND AFT AVIONICS BAY. NO DEFECTS NOTED. FLEW AIRCRAFT FOR 1 HOUR WITH NO ODORS DETECTED. I SUSPECT THAT PILOT FUELED AIRCRAFT AND SPILLED FUEL WHEN REFUELING POSSIBLY ON SHOES/FLIGHT SUIT CAUSING ODOR. AC WAS RETURNED TO SERVICE WITH NO OTHER REPORTED FUEL SMELL AFTER 16 HOURS OF FLIGHT TIME SINCE INCIDENT.
