## Discrepancy

(CAN) DURING CLIMBOUT, CREW REPORTED A BURNING TYPE ODOR, NO VISIBLE SIGN OF SMOKE. THEY ALSO REPORTED THE NR 1 PACK COULD NOT BE CONTROLLED IN AUTO OR MANUAL MODE. THE NR 2 PACK WAS ALREADY UNDER MEL.  FLIGHT RETURNED AND LANDED WITHOUT FURTHER INCIDENT.  DURING ACFT RUNS AT HANGER WE NOTED THAT THE NR 1 PACK WAS ABLE TO CONTROL IN AUTO AND MANUAL TO BOTH HOT AND COLD TEMPS.  NR 2 ACM FOUND SEIZED.  NR 2 ACM REPLACED.  ACM FUNCTION AND LEAK CHECKED SERVICABLE.
