## Discrepancy

ON FLIGHT 4419 THE CREW REPORTED THE FLIGHT ATTENDANT SMELLED ELECTRICAL BURNING IN PSU AT SEAT 7A, VERY SLIGHT ODOR.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  INSPECTED AND OPEN PSU.  NO ODOR NOTICED AT THIS TIME.  PERFORMED OPERATIONAL CHECK IAW AMM 33-25-00-700.  THE OPERATIONAL CHECK WAS GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
