Probable cause
The fracture of the number 1 high pressure turbine wheel due to fatigue, from an undetermined origin.

Analysis
During the takeoff roll, a Boeing 767-232, experienced an uncontained failure of the number 1 engine high pressure turbine wheel. Portions of the turbine disk exited the engine case, producing a 4-inch by 16-inch rupture. Pieces of the disk and the 2nd stage nozzle were fragmented and produced shrapnel like projectiles that pierced the engine core cowling and surrounding engine pylon mount. The first officer, flying the airplane, aborted and the takeoff and returned to the departure gate. Examination of the disk disclosed that it fractured due to fatigue from an undetermined origin.
