FAA to review Boeing 787s, but assures public it's safe

By Associated Press

POSTED:



WASHINGTON » The government stepped in Friday to assure the public that Boeing's new 787 "Dreamliner" is safe to fly, even as it launched a comprehensive review to find out what caused a fire, a fuel leak and other worrisome incidents this week.

Despite the incidents, Transportation Secretary Ray LaHood declared, "I believe this plane is safe, and I would have absolutely no reservations about boarding one of these planes and taking a flight." Administrator Michael Huerta of the Federal Aviation Administration said his agency has seen no data suggesting the plane isn't safe, but wanted the review to find out why safety-related incidents were occurring.

The 787 is the aircraft maker's newest and most technologically advanced airliner, and the company is counting heavily on its success. 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 molded to space-saving shapes compared with other airplane batteries. The plane is made with lightweight composite materials instead of aluminum.

A fire ignited 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.

On Friday, Japan's All Nippon Airways reported two new cases of problems with the aircraft. ANA spokes­woman Ayumi Kuni­ma­tsu said a small amount of oil was discovered leaking from an engine of a 787 flight from southern Japan's Miya­zaki airport to Tokyo.

The jet returned to Miya­zaki, and after checks found no safety risk, it flew to Tokyo. ANA said that 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, though it said it would comply with instructions from the FAA and other authorities.

The FAA review announced Friday, which will be conducted jointly with Boeing, will include the design, manufacture and assembly of the 787 with an emphasis on the plane's electrical power and distribution systems. The review will also examine how the plane's electrical and mechanical systems interact with each other.

There is no obvious trend or similarity to the problems, which suggests they are more likely the result of quality control than a design flaw, aviation safety experts said.
