## Discrepancy

ON 12/12/08 THE "FUEL BOOST PUMP ON R" AMBER CAS MESSAGE DISPLAYED IN FLIGHT.  THE MOTIVE FLOW PRESSURE SWITCH WAS REMOVED AND REPLACED AND THE SYS CHECKED OUT.  ON 12/13/08 THE SAME INDICATION CAME ON.  THE RT BLEED VALVE SOLENOID WAS REMOVED AND REPLACED AND THE SYS CHECKED OUT GOOD.  ON 12/25/08 THE SAME INDICATION OCCURRED INTERMITTENTLY DURING TAXI.  THE ENGINE WAS REMOVED AND REPLACED AT THIS TIME AND OPERATED NORMALLY.  ON 1/31/09 THE ORIGINAL ENGINE WAS RE-INSTALLED WITH A NEW FUEL CONTROL UNIT.  THE ACFT WAS RETURNED TO SERVICE WITH NO FURTHER INCIDENT.
