## Discrepancy

THE NR 1 ENGINE LOST POWER AT FL 180 AFTER DEPARTING.  THE AIRCRAFT WAS RETURNED TO IAH.  MAINTENANCE REMOVED AND REPLACED THE NR 1 ENGINE.  IN ADDITION, THE NR 1 AND NR 2 MLG BRAKES AND TIRES WERE REPLACED DUE TO HIGH ENERGY STOP.  *S/D* SHOP TEARDOWN REVEALED COMPLETE SEPARATION OF FIRST STAGE NOZZLE GUIDE VANES AS CAUSE OF FAILURE.
