## Discrepancy

DURING FINAL APPROACH AT 4000 MSL, THE NR 1 ENGINE FLAMED OUT.  ONE RAPID RESTART WAS ATTEMPTED BUT WAS UNSUCCESSFUL.  THE APPROACH AND LANDING WAS COMPLETED WITHOUT INCIDENT.  MAINTENANCE INSPECTED THE INLET AND EXHAUST WITH NO TROUBLE FOUND.  THE FUEL CONTROL AND 8TH STAGE PNEUMATIC CHECK VALVE WERE CHANGED.  THE FOLLOW-UP ENGINE RUN WAS NORMAL.
