## Discrepancy

CREW REPORTED THAT DURING CLIMB, AT APPROXIMATELY 3,000 FEET, THE MAIN PITCH TRIM WAS INOPERATIVE.  THE CREW FOLLOWED THE QUICK REFERENCE HANDBOOK AND RETURNED TO KMKE.  THE CREW ALSO REPORTED THAT THE BACK-UP PITCH TRIM WORKED AS NORMAL.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE RESET THE ELECTRICAL SYSTEM AND PERFORMED EMBRAER FIM TASK 27-43-00.  NO DEFECTS WERE FOUND AND OPERATIONAL CHECKS OF THE PRIMARY AND BACK-UP PITCH TRIM SYSTEMS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
