TOKYO -- Japan's transport minister said Tuesday that ministry officials launched a probe of Boeing's Dreamliner after a series of problems with the high-tech aircraft left travelers "enormously worried."

The ministry said late Monday it had chosen a team of experts to examine a Boeing (IW 500/16) 787 Dreamliner operated by Japan Airlines (JAL) that suffered two fuel leaks in less than a week.

A series of high-profile incidents over the last week are the latest problems to dog the aircraft, after production glitches delayed delivery of the first plane to All Nippon Airways (ANA) by three years.

JAL and rival ANA, Japan's two biggest airlines, are among Boeing's most important clients for the Dreamliner, with a combined more than 100 planes either already delivered or on order, in deals worth billions of dollars.

Problems bloomed last week with a fire on a JAL flight after it landed in Boston, the fuel leaks, and a cracked cockpit windshield that grounded one flight in Japan.

The Japanese probe comes after U.S. regulators on Friday announced an in-depth safety review of the plane.

"I think the Japanese people have become enormously worried after hearing almost every day" about problems with the Dreamliner, Transport Minister Akihiro Ota told a regular news briefing in Tokyo on Tuesday.

"It is important for us as the transport ministry to take a proactive approach and get a full grasp of the issue in order to provide a sense of safety and comfort to the public," he added.

The Dreamliner has been lauded by Boeing for a high-tech composite fiber body that reduces weight and improves fuel efficiency.
