On 8 September 2015, a catastrophic uncontained failure of a GE90-85B engine on a Boeing 777-200 taking off from Las Vegas was immediately followed by a rejected takeoff. A fuel-fed fire took hold and a successful emergency evacuation was completed. The Investigation traced the failure to a fatigue crack in the high pressure compressor well within the manufacturers estimated crack initiation life and appropriate revisions to risk management have followed. The main operational risk concern of the Investigation was the absence of any procedural distinction in crew emergency responses for engine fires beginning in the air or on the ground.
