## Discrepancy

WHILE IN CRUISE AT FL370, THE NR 4 ENGINE FLAMED OUT.  THE CREW FOLLOWED COM PROCEDURES AND RESTARTED THE ENGINE SUCCESSFULLY AT FL280.  ENGINE OPERATION WAS NORMAL FOR THE REMAINDER OF THE FLIGHT.  MAINTENANCE INSPECTED THE ENGINE AND PERFORMED AN ENGINE RUN TO HIGH POWER WITH NO DEFECTS OR ABNORMAL INDICATIONS.  THE ENGINE CONDITION MOTOR WAS REPLACED AS A PRECAUTION.
