US orders Boeing Dreamliner review

US regulators are conducting a comprehensive review of the design, manufacture and assembly of the Boeing 787 Dreamliner, even while government officials declared the plane safe. The move follows recent incidents including a fire and a fuel leak.

Michael Huerta, the Federal Aviation Administration administrator, told a Washington news conference today there is nothing in the data the agency has seen to suggest the plane is not safe, but the agency wants to find out why the safety-related incidents are occurring.

Transportation Secretary Ray LaHood went a step further: "I believe this plane is safe and I would have absolutely no reservations about boarding one of these planes and taking a flight," he said.

The 787, which Boeing calls the Dreamliner, is the aircraft maker's newest and most technologically advanced airliner. It relies more than any other modern airliner on electrical signals to help power nearly everything the plane does.

It's also the first Boeing plane to use rechargeable lithium ion batteries, which charge faster and can be moulded to space-saving shapes compared to other aircraft batteries. The plane is made with lightweight composite materials instead of aluminium.

A fire started on Monday in the battery pack of an auxiliary power unit of a Japan Airlines 787 empty of passengers as the plane sat on the tarmac at Boston's Logan International Airport. It took firefighters 40 minutes to put out the blaze. Also this week, a fuel leak delayed a flight from Boston to Tokyo of another Japan Airlines 787.

Today, Japan's All Nippon Airways reported two new cases of problems with the aircraft. A very small amount of oil was discovered leaking from the left engine of a 787 flight from southern Japan's Miyazaki airport to Tokyo.

The jet returned to Miyazaki, but after checks found no safety risk it flew to Tokyo. ANA said on another flight, to Matsuyama on the island of Shikoku, glass in a cockpit window cracked and the aircraft was grounded for repairs. ANA said it has no specific plan for inspections and will continue regular operations.

Boeing has insisted that the 787's problems are no worse than what it experienced when its 777 was new in the mid-1990s. That plane is now one of its top-sellers and is well-liked by airlines.

"Every new commercial aircraft has issues as it enters service," said Ray Conner, the president and chief executive of Boeing's commercial aircraft division, who joined Mr Huerta and Mr LaHood at the news conference. Boeing has delivered 50 of the 787s, starting in late 2011, and has orders for nearly 800 more. To get through the backlog, Boeing is ramping up production to build 10 787s per month by the end of the year.
