## Discrepancy

AIRCRAFT WAS REPORTED AS HAVING A YAW ON APPROACH WHEN REDUCING POWER ON THE ENGINES.  THE ROOT CAUSE WAS THE RT ENGINE FUEL CONTROL UNIT (FCU). THE FCU WOULD FLUCTUATE WHEN THE ACFT WAS ON APPROACH WHEN THE ENGINE POWER WAS BEING REDUCED.   FCU REPLACED AND A VERIFICATION FLIGHT PERFORMED.
