## Discrepancy

COMPONENT HAD BEEN RECENTLY INSTALLED TWO FLIGHT LEGS PRIOR.  CREW NOTICED THE UNIT DISPLAY FLASH AND A SUBSEQUENT SMOKE AND BURNING ODOR IN COCKPIT.  CIRCUIT BREAKER WAS PULLED AND DIVERTED.  UNIT WAS REMOVED AND INSPECTED AND WAS IDENTIFIED TO BE THE CAUSE OF THE ODOR.  A BURN MARK COULD BE SEEN ON A CIRCUIT BOARD THROUGH THE VENT IN THE CASE.  THE AFFECTED UNIT WAS REPLACED WITH NO FURTHER OCCURRENCE OF THE ISSUE.  NO PROBABLE CAUSE IS KNOWN TO US.  THESE UNITS (IVA-81A) ARE OBSOLETE AND NO LONGER SUPPORTED BY THE MFG.  THEY HAVE BEEN REPLACED BY A COMPATIBLE BUR UPGRADED PART (IVA-8D).  THIS SPECIFIC UNIT WAS SERVICED.
