## Discrepancy

AFTER FMS 1 FAILED, STARTED TO SMELL A BURNING PLASTIC TYPE OF ODOR. WHEN ADDING THROTTLE, COULD SMELL THE SCENT MORE, ESPECIALLY WHEN TAXING.  POWEREDACFT & TURNED ON ALL SYS & PERFORMED MULTIPLE ENG RUNS IAW MCCS REQUEST &  DIDN'T SMELL OR SEE ANY SIGNS OF BURNING PLASTIC. PERFORMED TORQUE CHK OF ACM IAW MM 21-52-13. RAN ALL SYSTEMS IN CABIN, MONITORED CONTROL SCREENS, & LIGHTS IAW MM 24-31-00. CONCLUDED THAT BUMING ODOR NOTED BY THE PILOTS WOULD HAVE BEEN FROM THE CDU 1 WHEN IT FAILED. NO FURTHER ACTION REQUIRED.
