Norwegian Air Says Both 787s Hit By Problems
Norwegian Air Shuttle suffered fresh technical problems with both its Boeing 787 Dreamliners on Sunday, the airline said, in another set of issues to hit the jet.
One of the planes remained grounded in Oslo on Monday due to problems with the oxygen supply to the cockpit, according to Norwegian Air spokeswoman Aasa Larsson.
"Technicians are working to fix the problem," she told Reuters news agency.
A valve had been repaired on the second plane on Sunday, and the delayed flight eventually left Oslo for New York.
"It has now landed there," Larsson said.
Technical problems have forced Norwegian Air to ground the planes several times in recent weeks, due to problems with brakes, hydraulic pumps and power issues.
The 787 was expected to be a game-changer for the aviation industry as its use of lighter materials and new engines promised 20 percent savings in fuel consumption.
But it has been troubled by delays in getting the planes into service and setbacks including the temporary grounding of all planes because of overheating batteries.
