## Discrepancy

DESCENDING THROUGH 10,000 MSL, THE THROTTLES WERE RETARDED TO IDLE.  THE RT ENGINE IMMEDIATELY ROLLED BACK AND SHUTDOWN.  LEFT THROTTLE WAS ADVANCED TO MAINTAIN AIRSPEED AND ALTITUDE.  IGNITIONS WERE TURNED ON IAW THE CHECKLIST AND THE RT ENGINE STARTED BACK UP.  ONCE ENGINES STABILIZED, DESCENT CONTINUED AND A NORMAL LANDING AT DESTINATION FOLLOWED.  INVESTIGATION FOR THE ROOT CAUSE IS STILL ONGOING.  SUSPECTING THE FUEL CONTROL UNIT AS THE FAILED COMPONENT.
