An American Airlines jetliner that suffered an “anomaly” in the braking system before running past the end of a runway in Texas last month had undergone a brake-replacement job four days earlier, U.S. investigators said Thursday.
An inspection showed that flexible hydraulic lines to parts of the braking system on the Boeing 737 had been improperly reconnected, the National Transportation Safety Board said in a preliminary report on the Feb. 10 incident at Dallas-Fort Worth International Airport.
