## Discrepancy

AFTER TURNING ON THE NR 1 PACK THE CREW NOTED A ODOR SIMILAR TO MELTING PLASTIC.  MAINTENANCE INSPECTED THE AIRCRAFT AND FOUND THE NR 1 AIR CYCLE MACHINE TO BE THE SOURCE OF THE ODOR.  THE AIR CYCLE MACHINE WAS REPLACED, OPERATIONAL CHECKS WERE PERFORMED AND THE DISCREPANCY WAS CLEARED.
