MIAMI — An American Airlines Boeing 767-300(ER) operating flight AA383 to Miami, caught fire on runway 28R at Chicago O’Hare International Airport after aborting its take-off.

The airline reported the rejected take-off was executed due to an engine-related issue. 161 passengers and nine crew were rapidly evacuated via slides and bused to the terminal. The carrier will operate a special flight on Friday night to take the passengers to Miami.

Twenty passengers and one flight attendant reported non-critical injuries. Several were transported to Chicago-area hospitals to be evaluated.

American Airlines deployed its CARE Team to those hospitals and Chicago O’Hare International Airport to provide assistance for our customers, crew members and their families.

Flightradar24 data shows the aircraft reached 115kts before decelerating and coming to a complete stop.

It took fire crews only a few minutes to bring the fire under control, officials said.  As the smoke cleared, the right wing could be seen sagging and touching the tarmac. The right horizontal stabilizer also experienced damage due to the heat.

The aircraft involved in the incident (N345AN • MSN 33084 • LN 906) was built in 2003, and is among American’s youngest planes of that model. At the moment of the incident, the aircraft had logged 8,120 cycles and 50,632 flight hours.

The incident occurred when O’Hare International Airport was conducting fire drills, and told people on social media to not to be afraid if they saw anything unusual.

The airport remained operational on its north side. Runways 28R stills closed to traffic while runway 28C was opened at 17:30 local Chicago time.

On October 29th, 2016 the National Transportation Safety Board (NTSB) reported that an examination of the right engine revealed the Number 2 stage high pressure turbine (HPT) disk failed. A large disk fragment landed in an UPS warehouse about 2,920 feet (890m) from the aircraft.

So far, about 90% of the disk was recovered, including another piece found 1,823 feet (556m) from the accident site. The damage to the fuselage was limited to windows and cosmetic interior, and there was no fire in the passenger cabin.

On November 4th, 2016 the NTSB issued an Investigative Update in which reports that at the moment of the incident, the Boeing 767-300 was accelerating for takeoff through 128 Knots-Indicated Air Speed (KIAS) with the engines set at takeoff power thrust setting. Two seconds after the failure, the power levers were retarded at 134 KIAS and brake pressures began to increase as autobrakes activated and speedbrakes automatically extended.

The aircraft came to a full stop about 25 seconds later 9,225 feet (2,811m) past the runway threshold, with a pool fire below its right wing fed by a fuel leak.

The NTSB also reported that the stage two HPT disk of the right engine failed and fractured into at least four pieces. The majority of the disk was collected and sent to Washington D.C. for further examination.

Preliminary results so far show one of the fractures with indications of fatigue cracking, initiated at an internal inclusion, near the forward side of the hub’s inner bore. Ongoing metallurgical examinations of the disk will focus on detailed characterization of the inclusion and the fracture surfaces, the NTSB said.
