Improper maintenance was to blame for a Boeing 737 brake failure that prevented the crew from stopping the airplane before it rolled onto the paved overrun area beyond the threshold of Runway 17L at Dallas-Fort Worth International Airport (DFW), the U.S. National Transportation Safety Board (NTSB) says.
None of the 104 passengers and crew in the American Airlines 737-800 was injured in the Feb. 10, 2024, overrun, which caused minor damage to the airplane. All 104 occupants exited using the airstairs.
In its final report on the incident, the NTSB said the probable cause was “improper maintenance due to human error during a braking system modification.” The improper maintenance resulted in diminished braking performance, the NTSB said. The board cited as a contributing factor “the lack of a functional check to verify the flexible hydraulic hoses and transducer wiring were connected correctly after the braking system modification.”
