Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Airframe/component/system failure/malfunctionTakeoff - roll/run
Turbine assembly,turbine blade - fatigueCause
Turbine assembly,turbine blade - failure,totalCause
Turbine assembly,turbine wheel - failure,total
Turbine assembly,shaft bearing - failure,total
Fluid,oil - burned

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
