## Discrepancy

DURING CRUISE FLIGHT, PILOT NOTED SMOKE FROM BEHIND THE INSTRUMENT PANEL, ODOR OF BURNED RUBBER, AND THE GTN-650 WAS FLASHING.  DURING MAINTENANCE INSPECTION,  FOUND A VENT AREA DRAIN LINE CLOGGED WHICH CAUSED WATER TO BUILDUP IN THE VENT AREA. WIRING WAS INSPECTED, THE GTN-650 WAS INSPECTED AND NO MOISTURE OR WIRING DEFECTS IN THOSE AREAS WAS NOTED. PERFORMED A 15 MINUTE GROUND RUN AND OPS CHECK OF SYSTEMS WITH NO FURTHER DEFECTS NOTED.
