## Discrepancy

TOOK OFF AND WAS ON INITIAL CLIMB, NOTICED A FLASH AND SMELLED AN ODOR. RETURNED TO DEPARTURE AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED THE AIRCRAFT AND DISCOVERED THAT A BRAIDED AIRFRAME BONDING GROUND STRAP HAD CHAFED INTO A WIRE GOING TO THE PROPELLER HEAT CONTROLLER. THE CHAFED WIRE WAS REPAIRED AND THE BONDING JUMPER SECURED AWAY FROM ANY OTHER WIRING CIRCUITS, AND THE AIRCRAFT WAS RETURNED TO SERVICE.
