## Discrepancy

MANUFACTURER INDICATES A FAILED BRAZE WELD ON THE #1 LPT NOZZLE GUIDE VANE WHICH ALLOWED THE NOZZLE TO FLEX AND CONTACT THE #1 LPT DISK.  THIS DAMAGED THE DISK SENDING DEBRIS THROUGH THE REST OF THE TURBINE SECTION CAUSING DAMAGE THROUGHOUT.  ENGINEERING IS INVESTIGATING IF THE FAILED WELD WAS THE ROOT CAUSE OR THE RESULT OF SOME OTHER FAILURE, POSSIBLY VIBRATION FROM A BEARING.  AFTER REPAIR OF ENGINE NOTED FAILED PART WAS A NOZZLE/HEATSHIELD ASSY.
