## Discrepancy

CLT - FLT 306 - JUST AT ROTATION, WHILE TAKING OFF FROM CLT, THE FIRST OFFICERS ADI CIRCUIT BREAKER TRIPPED.  CREW RESET THE CIRCUIT BREAKER BUT IT TRIPPED AGAIN.  CREW ELECTED TO RETURN TO FIELD AT CLT.  FLIGHT LANDED WITHOUT INCIDENT.  NO EMERGENCY WAS DECLARED.  MAINTENANCE REMOVED AND REPLACED THE FIRST OFFICERS ADI.  OPERATIONAL CHECK GOOD.  (M)
