## Discrepancy

WHILE TAXING FOR TAKEOFF THE CIRCUIT BREAKER POPPED.  CREW RESET IT AND CONTIUNED THE FLIGHT.  ABOUT 1 HOUR INTO THE FLIGHT THE CIRCUIT BREAKER POPPED AGAIN THE CREW RETURN TO THE AIRFIELD AND TERMINATED THE FLIGHT.  THE TECH CHECKED THE WIRING WITH A VOLTAGE REGULATOR AND FOUND THE WIRING WAS FINE.  REPLACED THE ELECTRIC FUEL PUMP.
