## Discrepancy

UPON TAKEOFF THE PILOT NOTICED A BURNED ODOR IN THE COCK-PIT.  ALL CIRCUIT BREAKERS WERE IN, NOTHING TRIPPED.  PILOT NOTICED THAT THE TRANSPONDER WAS DISPLAYING A "FAILURE" ON THE SCREEN.  TURNED POWER OFF TO TRANSPONDER, AND CAME BACK AROUND FOR A SAFE LANDING.  MX DETERMINED THAT THE BURNED ODOR WAS IN FACT COMING FROM THE TRANSPONDER.
