Federal regulators have grounded all U.S. Boeing 787 Dreamliner passenger jets, a potentially devastating setback for the company's troubled new flagship airliner.
The move Wednesday by the Federal Aviation Administration left airlines reeling, seeking ways to accommodate delayed passengers. Boeing Co. stock fell on the news in after-hours trading.
The order came Wednesday after a 787 operated by a Japanese carrier, All Nippon Airways, made an emergency landing in southwestern Japan. The crew reported an unusual smell in the cabin, and indicators in the cockpit told pilots there was a problem related to an onboard lithium-ion battery.
FAA statement on Boeing 787 grounding
Such batteries were also involved in a fire last week aboard a parked 787 in Boston operated by Japan Airlines.
The Japanese carriers — which own 24 of the 50 Dreamliners flying today — decided to remove all of their 787s from service indefinitely out of safety concerns. That move led to the FAA's extraordinary grounding order.
The plane is assembled at Boeing's Everett, Wash., factory, but the bulk of the large components arrive from suppliers around the world pre-assembled. There are about 50 suppliers in California alone.
"This is clearly a black eye and hiccup for Boeing," said Richard Phillips, managing director at Janes Capital Partners, an Irvine-based aerospace and defense investment bank. "It's clearly related to the batteries.... It could mean significant reengineering work that … could take a long time."
Boeing Chief Executive Jim McNerney said in a statement that the company is working with the FAA to "find answers as quickly as possible."
"The company is working around the clock with its customers and the various regulatory and investigative authorities," he said. "We are confident the 787 is safe, and we stand behind its overall integrity."
The FAA's decision came less than a week after U.S. Transportation Secretary Ray LaHood and FAA chief Michael Huerta deemed the plane safe to fly. The 787 has experienced a series of mishaps including a fuel leak and the Boston fire. However, the FAA had allowed the planes to continue to operate while it launched an unusual and sweeping evaluation of the way Boeing designs, manufactures and assembles the aircraft.
At issue is the Dreamliner's electrical systems and power-distribution panels, which involves pervasive use of lithium-ion batteries, which have been involved in fires and can also be found in cellphones and electric automobiles. The Dreamliner is the first large commercial aircraft to use the technology on such a large scale.
In a statement, the FAA said that the grounding order is aimed to "address a potential battery fire risk in the 787 and require operators to temporarily cease operations. Before further flight, operators of U.S.-registered Boeing 787 aircraft must demonstrate to the Federal Aviation Administration that the batteries are safe."
The FAA order is expected to be followed by carriers worldwide.
Boeing's use of lithium-ion batteries, made by Kyoto, Japan-based GS Yuasa Corp., were called into question when a smoldering fire was discovered last week on the underbelly of a Dreamliner operated by Japan Airlines after the 173 passengers and 11 crew members had deplaned at the gate.
In the latest incident involving All Nippon Airways, smoke was seen swirling from the right side of the cockpit. All 137 passengers and crew were evacuated from the aircraft and slid down the Dreamliner's emergency slides. Video of the event was captured by an onboard passenger and has been broadcast worldwide.

The FAA has been aware of the flammability of lithium-ion batteries for years. Still when the agency was certifying the Dreamliner for flight operation, it issued special conditions for lithium-ion battery installations on the Dreamliner because regulations don't cover this technology.
"At present, there is limited experience with use of rechargeable lithium-ion batteries in applications involving commercial aviation. However, other users of this technology, ranging from wireless telephone manufacturing to the electric vehicle industry, have noted safety problems with lithium ion batteries. These problems include overcharging, over-discharging, and flammability of cell components," the FAA wrote at the time.
The FAA has issued scathing assessments of lithium-ion batteries for starting fires.
In October 2011, the FAA issued an airworthiness directive to owners of Cessna Aircraft Co.'s Model 525C airplanes that required them to swap out the lithium-ion batteries with other batteries.
"We are issuing this … to prevent a potential battery fault that could lead to an aircraft fire," the directive said.
In a teleconference with reporters last week, Boeing's chief engineer on the Dreamliner Mike Sinnett said that a lithium-ion battery was not the only choice of battery, but that "it was the right choice."
