Analysis 

NTSB investigators traveled in support of this investigation and used data obtained from various sources to prepare this aircraft accident report.

The NTSB's full report is available at http://www.ntsb.gov/investigations/AccidentReports/Pages/AccidentReports.aspx. The Aircraft Accident Report number is NTSB/AAR-18/01.

On October 28, 2016, about 1432 central daylight time, American Airlines flight 383, a Boeing 767-323, N345AN, had started its takeoff ground roll at Chicago O'Hare International Airport, Chicago, Illinois, when an uncontained engine failure in the right engine and subsequent fire occurred. The flight crew aborted the takeoff and stopped the airplane on the runway, and the flight attendants initiated an emergency evacuation. Of the 2 flight crewmembers, 7 flight attendants, and 161 passengers on board, 1 passenger received a serious injury and 1 flight attendant and 19 passengers received minor injuries during the evacuation. The airplane was substantially damaged from the fire. The airplane was operating under the provisions of 14 Code of Federal Regulations Part 121. Visual meteorological conditions prevailed at the time of the accident. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The failure of the high-pressure turbine (HPT) stage 2 disk, which severed the main engine fuel feed line and breached the right main wing fuel tank, releasing fuel that resulted in a fire on the right side of the airplane during the takeoff roll. The HPT stage 2 disk failed because of low-cycle fatigue cracks that initiated from an internal subsurface manufacturing anomaly that was most likely not detectable during production inspections and subsequent in service inspections using the procedures in place. Contributing to the serious passenger injury was (1) the delay in shutting down the left engine and (2) a flight attendant's deviation from company procedures, which resulted in passengers evacuating from the left overwing exit while the left engine was still operating. Contributing to the delay in shutting down the left engine was (1) the lack of a separate checklist procedure for Boeing 767 airplanes that specifically addressed engine fires on the ground and (2) the lack of communication between the flight and cabin crews after the airplane came to a stop.

U.S. air-accident investigators have called for upgraded engine-inspection practices and better-coordinated procedures for passenger evacuations, in their final report about a fire that badly damaged an American Airlines Group Inc. jet on a Chicago runway two years ago.

The findings and recommendations released by the National Transportation Safety Board on Tuesday stem from an October 2016 accident in which a rare manufacturing defect caused part of the right engine on a Boeing Co. 767 bound for Miami to rupture violently late in the takeoff roll. Metal parts flew as far as 3,000 feet, a fuel leak caused a massive fire under the right wing and all 161 passengers used emergency slides to leave the jet.


There were no fatalities, but the National Transportation Safety Board issued industrywide recommendations for modernized engine inspections and stepped-up airline crew training to ensure safer emergency evacuations.


According to the National Transportation Safety Board, United States regulators haven’t updated guidance on conducting emergency evacuations for three decades, despite several high-profile examples of problems getting passengers off airliners in just the past few years.


Investigators concluded that a rare manufacturing flaw dating back to the late 1990s—and likely undetectable through recent years—created microscopic cracks in the high-energy internal disc that eventually led to the accident at O’Hare International Airport. General Electric Co. manufactured the engines.


Even with significant safety advances in engines and overall airline performance over the last few decades, “there’s still improvements that can be made,” said Robert Sumwalt, the safety board’s chairman. Inspection methods “that can fail to uncover a defect in a safety critical component of an airliner,” he said, “need a closer look.:


Regarding the crew’s response, the National Transportation Safety Board concluded that the pilots, after hearing a loud bang, acted appropriately to halt the takeoff and shut down the damaged engine. But the report was critical of the level of cooperation between the cockpit crew and flight attendants.


Investigators, among other things, found that flight attendants hadn’t received adequate training on systems to communicate with the cockpit or passengers. Two attendants told the safety board they couldn’t operate the intercoms to contact the pilots, as smoke billowed inside the cabin and passengers disregarded instructions by climbing over seats and insisting on grabbing carry-on bags.


With one of the wide-body jet’s engines still running as the evacuation began, a passenger suffered a serious injury as he was hit by jet blast. The pilots told investigators the only emergency engine shut-off checklist they had didn’t call for immediately turning off the remaining engine.


Modern jet turbines are designed to prevent broken parts from being spewed outside the engine cover. But violent disintegration of some internal parts has dogged certain models of GE’s CF6-80 model engines since 2000, prompting a series of stepped-up safety actions by the manufacturer and the Federal Aviation Administration.


An Federal Aviation Administration spokeswoman didn’t have any immediate comment on the nonbinding safety recommendations.


American, which has revamped flight attendant training, told investigators the cabin crew took appropriate steps to initiate the evacuation despite communication difficulties.

NTSB Identification: DCA17FA021 
 Scheduled 14 CFR Part 121: Air Carrier
Accident occurred Friday, October 28, 2016 in Chicago, IL
Aircraft: BOEING 767, registration: N345AN
Injuries: 1 Serious, 19 Minor, 150 Uninjured.

This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

On October 28, 2016, at about 2:32 CDT, American Airlines flight number 383, a Boeing B767-300, N345AN, powered by two General Electric CF6-80C2B6 turbofan engines, experienced a right engine uncontained failure and subsequent fire during the takeoff ground roll on runway 28R at the Chicago O'Hare International Airport (ORD), Chicago, Illinois. The flightcrew aborted the takeoff and stopped the aircraft on runway 28R and an emergency evacuation was conducted. Of the 161 passengers and 9 crew members onboard, one passenger received serious injuries during the evacuation and the airplane was substantially damaged as a result of the fire. The flight was operating under the provisions of 14 Code of Federal Regulations Part 121 as a domestic scheduled passenger flight to Miami International Airport (MIA), Miami, Florida.
==========

Late last month, passengers on a Chicago to Miami flight were sent hurtling down evacuation slides from an American Airlines Boeing 767 after the plane’s engine caught fire, engulfing the runway in billowing black smoke.

Now, 18 passengers — including three from South Florida — are suing the airline, Boeing and GE, the engine’s manufacturer, for the injuries caused by the allegedly “defective and unreasonably dangerous” aircraft, the suit says. The lawsuit was filed in Illinois circuit court, where the incident took place.

On the afternoon of Oct. 28, 170 crew and passengers on Flight 383 from Chicago’s O’Hare International Airport to Miami International Airport were forced to evacuate when the engine on the right side of the plane burst into flames on the tarmac. Footage from the scene shows passengers quickly evacuating on slides on the front and rear left side of the plane and running into a grassy area while smoke and fire rise in the background. The plane’s right wing can be seen melting and drooping.

About 20 people suffered minor injuries, officials said.

According to the lawsuit, the plaintiffs suffered “personal and bodily injuries, both physical and psychological in nature” and either have or will sustain “future medical bills, lost earnings, disability, disfigurement, and pain and suffering and emotional distress,” as a result of the accident.

The suit claims GE sold the defective engine to Boeing, which was negligent in “designing, manufacturing, assembling, and selling the accident aircraft as as not to cause injury to plaintiffs.” It also alleges that American Airlines failed to maintain, service, inspect and repair the aircraft appropriately enough to avoid the accident.

American Airlines declined to comment, citing pending litigation.

The plaintiffs are represented by Chicago-based Wisner Law Firm, which focuses solely on representing people injured or killed in aviation accidents. The firm recently resolved a similar case for an undisclosed amount involving more than 100 passengers and crew on a September 2015 British Airways. Like the Chicago to Miami flight, the British Airways flight involved a faulty GE engine on a Boeing plane that failed and caught fire at Las Vegas’ McCarran International Airport.

“GE and Boeing and American, as well, need to take a harder look at this problem because I’m concerned it’s a recurring problem,” said Floyd Wisner, principal at the law firm. “It’s not just a rare occurrence.”

The law firm expects to add other passengers as plaintiffs, as well as other parties, such as material suppliers or component manufactures, as defendants if certain parts of the engine are found as contributing to the fire.

  1. More frivolous lawsuits. People were not badly injured and they still want to get something just because they can. Kudos to the crew and emergency crews. Thumbs down to the few passengers trying to cash in. Sign of the times unfortunately.
