American Airlines Flight 383 Boeing 767-300 Engine Failure and Evacuation at Chicago O’Hare

On October 28, 2016, American Airlines Flight 383, a Boeing 767-300 scheduled from Chicago O’Hare International Airport to Miami, experienced an engine-related event during the takeoff roll. The takeoff was aborted and passengers evacuated using slides while fire was reported near the aircraft. Federal investigators examined the engine malfunction sequence, the on-ground fire, and the evacuation process to determine the factors that contributed to the event and resulting injuries.

Accident Summary

What Happened on American Airlines Flight 383

According to the legacy reporting, the aircraft experienced a “problem during takeoff” that American Airlines described as an engine malfunction. Additional reporting referenced a serious engine failure involving engine parts separating and behaving as debris or “shrapnel.” The flight crew rejected the takeoff and stopped the aircraft on the runway, and an evacuation using slides followed while fire was reported near the aircraft.

Injuries were reported during the event and evacuation, including reports of up to 21 injured passengers and at least one crewmember, with transport to a local hospital. Events involving rejected takeoff and slide evacuation frequently prompt investigation into both the initiating mechanical condition and the evacuation decision-making and execution.

Aircraft and Operational Context

The Boeing 767-300 is a twin-engine transport-category aircraft. During takeoff, engine malfunctions can create rapid operational decision points because takeoff performance margins and stopping distance considerations change as speed increases. Investigators generally examine whether the event occurred below or above decision speed thresholds, what cockpit indications were available, and how the crew executed checklist and rejected takeoff procedures.

When reports describe engine debris separation and a fire condition, investigators typically examine whether the event involved an uncontained failure mode and whether the engine nacelle and containment structures performed as designed. The presence of fire on the ground also raises questions about fuel, oil, or accessory system involvement and the timeline between the mechanical failure, aircraft stop, and evacuation.

Accident Investigation

The National Transportation Safety Board opened an investigation into the event. NTSB investigations typically involve examination of damaged engine components, review of maintenance and inspection history, and analysis of operational data and communications. A practical overview of how federal investigations proceed is provided in our discussion of the NTSB investigation process.

In a takeoff-phase engine failure with reported fire and evacuation, investigators commonly evaluate (1) the engine failure sequence and component condition, (2) whether any fragments exited the engine and caused secondary damage, (3) the source and progression of any fire, and (4) the decision-making and execution of the evacuation, including timing, door/slide selection, and passenger flow.

Where injuries occur, investigators and operators often review whether injuries resulted primarily from the initiating event, from smoke or fire exposure, or from slide evacuation dynamics. Slide evacuations can reduce risk when a credible external hazard exists, but they can also produce injuries, making the decision and execution an important safety topic in investigative review.

Operational and Regulatory Issues

Rejected takeoff events involving fire frequently trigger review of aircraft performance, emergency response, and airport rescue and firefighting (ARFF) coordination. Investigators may examine whether airport response resources were positioned effectively, how quickly the fire condition was addressed, and whether evacuation and passenger movement off the runway environment were managed safely.

Where a failure mode involves engine debris or containment concerns, regulatory questions can include whether the relevant inspection and maintenance regimes were adequate and whether the event reflects a broader reliability or design issue. At an early stage, these questions are evaluated through evidence development rather than assumptions about cause.

Aviation Accident Litigation

Serious on-ground engine failures, fires, and evacuations can raise complex technical and regulatory questions involving engine design and maintenance, operational decision-making, emergency response, and passenger injury mechanisms. A general overview of how these matters are evaluated is provided in our discussion of aviation accident litigation.
