B763, Chicago O'Hare IL USA, 2016

Summary

On 28 October 2016, an American Airlines Boeing 767-300 made a high speed rejected takeoff after an uncontained right engine failure. A successful emergency evacuation of the 170 occupants was completed as a major fuel-fed fire destroyed the failed engine and substantially damaged the aircraft structure. The failure was attributed to an undetected sub-surface manufacturing defect which was considered to have escaped detection because of systemically inadequate materials inspection requirements rather than any failure to apply existing practices. Safety issues in relation to an evacuation initiated by cabin crew following a rejected takeoff and fire were also examined.
