DENVER — A United Airlines 787 Dreamliner was diverted early Sunday due to a mechanical problem, the second such incident for the plane in a week.
United flight 94 was on its way to Denver when it was forced to fly back to the place from where it left: Houston, United Airlines said.
The cause: an issue with the brake indicator.
The plane landed without incident and with no passenger injuries, said Boeing, which makes the Dreamliner.
On Tuesday, another United Airlines Dreamliner flight made an unscheduled landing.
That flight was on its way from Denver to Tokyo, when it was diverted to Seattle because of a problem with its oil filter.
The incidents come six months after the FAA and other officials grounded the Dreamliner worldwide due to troubles with its battery system.
“The 787 is a great airplane and we know it will continue to receive heightened attention when reliability events occur in service,” Boeing spokeswoman Yvonne Leach said Sunday.
The 787 Dreamliner began service in the U.S. in 2012.
The entire global fleet of 50 Dreamliners was grounded in January after two battery overheating incidents triggered concerns among safety officials.
Among the Dreamliner’s innovative new designs is a battery system that uses new, lighter lithium-ion batteries.
In April, the Federal Aviation Administration (FAA) ordered all 787 operators to make specific modifications and United has been flying its fleet of six 787s since May 20.
United is the sole domestic operator of the airplane, which boasts high fuel efficiency due to the light-weight carbon-composite materials used in its wings and fuselage.
In an apparent show of confidence in the new airliner, United announced Tuesday it was ordering 20 additional Dreamliners, specifically the 787-10 model, which is a longer version of the plane.
The plane represents a new generation of efficient wide-body, long-range airliners, helping to make it among the world’s most watched aircraft.
Airlines worldwide have committed to buy the plane, and hundreds of millions of dollars are riding on Dreamliner’s success. Boeing’s rival Airbus flew a similar airliner, its highly anticipated A350 XWB, for the first time on Friday at its facility in Toulouse, France.
