## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Airframe/component/system failure/malfunction, takeoff - roll/run
  - turbine assembly,turbine blade - fatigue (cause)
  - turbine assembly,turbine blade - failure,total (cause)
  - turbine assembly,turbine wheel - failure,total
  - turbine assembly,shaft bearing - failure,total

## Analysis

DURING THE GROUND RUN FOR TAKEOFF A FATIGUE PRECIPITATED FAILURE OF THE THIRD STAGE TURBINE BLADE OCCURRED WITH SECONDARY DAMAGE TO SEVERAL GUIDE VANES AND THE FOURTH STAGE TURBINE WHEEL. IMBALANCE OF THE TURBINE WHEEL CAUSED THE FAILURE OF THE NUMBER SIX BEARING ALLOWING OIL TO LEAK INTO THE EXHAUST AREA CAUSING A LOW INTENSITY FIRE
