A Boeing 787 Dreamliner jet was forced to make an emergency landing during an internal US flight on Sunday, due to a problem with its brake system, United Airlines said in a statement.
"United flight 94 from Houston to Denver returned to Houston Sunday due to a brake indicator issue," the US carrier said.
"Following standard operating procedures, as a precautionary measure, the flight landed in emergency status. The aircraft landed safely at 11:58 a.m. C.T. and our maintenance team is conducting a review of the aircraft," the statement continued.
A Boeing spokeswoman said the problem with the braking system forced the plane "back to base," without giving details of the malfunction or how long it might take to repair it.
Leach said a Boeing field service representative was on the scene in Houston to help the airline with the issue, including getting the airplane back into service and acdealing with stranded passengers.
The fleet of Dreamliners was grounded earlier this year when problems were discovered with its battery systems.
