The National Transportation Safety Board (NTSB) yesterday opened the public docket releasing more than 500 pages of information as part of its ongoing investigation into the October 2016 uncontained engine failure on a commercial jetliner in Chicago.

On October 28, 2016, at 2:32 p.m. CDT, a Boeing 767-300 (registration N345AN), a scheduled American Airlines flight bound for Miami, Fla., experienced a right engine uncontained failure and subsequent fire during the takeoff ground roll on runway 28R at the Chicago O'Hare International Airport. The flightcrew aborted the takeoff and stopped the aircraft on the runway and an emergency evacuation was conducted. Of the 161 passengers and 9 crew members onboard, one passenger received serious injuries during the evacuation. The airplane was substantially damaged by the fire.

The docket includes the transcript of the cockpit voice recorder, interview transcripts and summaries, factual reports, a video of the emergency evacuation, and other investigative material.

The public docket contains only factual information collected by NTSB investigators, and does not provide analysis, findings, recommendations or probable cause determinations. No conclusions about how or why an accident or incident occurred should be drawn from the docket. The docket opening marks a transition in the investigative process where the majority of facts needed for the investigation have been gathered and the NTSB can move ahead with analysis of those facts. Opening the docket affords those with a need and desire for its contents the opportunity review what factual information has been gathered about the accident. Any analysis, findings, recommendations, or probable cause determinations related to the accident will be issued by the Board at a later date.
