 NTSB Opens Docket on Michigan Aviation Accident Investigation

WASHINGTON (April 11, 2018) — The National Transportation Safety Board opened the public docket Wednesday on its ongoing investigation of a runway excursion accident involving a chartered jetliner in Michigan.

On March 8, 2017, an Ameristar Air Cargo Inc. flight 9363, a Boeing MD-83, ran off the end of runway 23L after executing a rejected takeoff at Willow Run Airport in Ypsilanti, Michigan. All 109 passengers and seven crewmembers evacuated the airplane. One passenger was reported to have received a minor injury. The airplane, which was substantially damaged, was an on-demand charter flight and was destined for Washington Dulles International Airport in Virginia.

The docket contains over 800 pages of factual information including: investigative group reports, interview summaries, surveillance video and a transcript of the cockpit voice recorder.  It does not provide analysis, findings, recommendations or probable cause determinations.  No conclusions about how or why an accident 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 to 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.
