## Discrepancy

(CAN) THE FLIGHT CREW REJECTED TAKEOFF DUE TO NR 1 ENGINE EXHIBITING AN EXCESSIVE VIBRATION INDICATION, AS WELL AS A LOUD BUZZING SOUND. THE VIBRATION REMAINED WHEN POWER WAS REDUCED TO GROUND IDLE. THE ENGINE WAS REPLACED AND THE AIRCRAFT WAS RETURNED TO SERVICE. INITIAL TEARDOWN REVEALED THE FAILURE OF ONE GUIDE VANE OF THE FIRST NOZZLE, WITH SUBSEQUENT DOWNSTREAM DAMAGE. A FINAL DETERMINATION OF CAUSE IS PENDING.
