NEW YORK (AP) -- Boeing is facing another problem with its new 787 Dreamliner.
A 787 operated by Poland's LOT airline made an unscheduled landing Sunday in the capital of Iceland because of a malfunctioning antenna.
The plane was traveling from Toronto to Poland when it was diverted to Reykjavik, about 1,700 miles short of its destination.
A Boeing spokesman says LOT sent parts and personnel to Iceland to fix the problem. He says Boeing is ready to help if needed.
Even before Sunday's incident, LOT had reported technical problems with the 787 and demanded that Boeing try to solve a potential safety threat.
The landing in Iceland came a day after a Norwegian Air Shuttle ASA Dreamliner was grounded for an unspecified technical problem.
Boeing's 787 Dreamliner plane has been plagued by a series of technical glitches since it was introduced in September 2011. The worldwide fleet of about 50 planes was grounded for almost four months this year after lithium batteries smoldered on two planes in January.
