## Discrepancy

SHORTLY AFTER INITIATING DESCENT FROM FL430, AND EVENTUALLY AT FLIGHT IDLE, EXPERIENCED TWO SHORT BURSTS OF ENGINE VIBRATION, AND NOTICED THAT THE CYAN ENGINE SHUTDOWN R CAS MESSAGE BRIEFLY DISPLAYED THEN EXTINGUISHED.   NO FURTHER VIBRATIONS WERE FELT DURING THE REST OF THE DESCENT, PRESSED THE EVENT MARKER A FEW SECONDS AFTER THIS OCCURRED. //// CORRECTIVE ACTION //// REPLACED THE LT ENGINE GENERATOR DUE TO AC BEARING EICAS MESSAGE. REPLACED RT ENGINE BOV SOLENOID DUE TO COMPRESSOR SURGING.
