The Australian Transport Safety Bureau (ATSB) has found that fatigue cracking in the blade slots of a high-pressure turbine disk led directly to the uncontained failure of the left General Electric CF6-80A engine of an Air New Zealand Boeing 767 aircraft that occurred near Brisbane on 8 December 2002. As a result of the investigation findings, the engine manufacturer has implemented changes to the disk manufacturing and repair processes and has revised the inspection requirements for the disks fitted to the affected engine model.
