## Discrepancy

THE CREW REPORTED AN ELECTRIC BURNING ODOR AND SMOKE IN THE COCKPIT DURING FLIGHT. THE ACFT LANDED WITHOUT INCIDENT WHERE MAINTENANCE INSPECTED THE ACFT AND FOUND THE NR 1 ACM TO BE FROZEN.  MAINTENANCE PLACED THE NR 1 PACK ON MEL, AND THE ACFT WAS APPROVED FOR RETURN TO SERVICE.  MAINTENANCE R & R THE NR 1 ACM, OPERATIONALLY TESTED WITH NO DEFECTS, REMOVED THE MEL, AND THE ACFT WAS APPROVED FOR RETURN TO SERVICE.
