Deepening Crisis for the Dreamliner

The 137 passengers and crew members aboard Flight NH692 from Ube, in western Japan, to Tokyo used emergency slides to leave the aircraft early Wednesday after battery trouble and an “unusual smell” in the cockpit prompted its pilots to land instead at Takamatsu airport, according to All Nippon, or A.N.A. The jet’s main battery in the front of the plane was later found to have become discolored and to be seeping electrolyte fluid, All Nippon said.

The public broadcaster, NHK, said smoke had entered the cockpit, although All Nippon could not confirm that report. One passenger was taken to a hospital with hip pain but was later discharged, All Nippon said.

The emergency landing followed a string of problems in the past month with the Boeing 787, known as the Dreamliner, including a battery fire, fuel leaks and a cracked cockpit window. All Nippon said the problems Wednesday involved the same lithium-ion batteries that caught fire last week in Boston on a Dreamliner operated by Japan Airlines.

Ryosei Nomura, a spokesman for All Nippon, said Wednesday that the airline was temporarily grounding all 17 of its Dreamliners for inspections, leading to the cancellation of 38 domestic and international flights. Japan Airlines also said in a news release that it would ground the five Dreamliners it was operating; two other aircraft were already undergoing safety checks.

Akihiro Ota, the Japanese transportation minister, said that the emergency landing had raised concerns about the Dreamliner’s safety and that he would dispatch officials to investigate. “I see this as a serious incident which could have led to a serious accident,” Mr. Ota said in Tokyo.

Osamu Shinobe, vice president of All Nippon, said at a news conference at Haneda Airport in Tokyo, “I apologize for the grave concern and trouble we have caused our passengers, their families and others.” He said the airline was still investigating.

All Nippon and Japan Airlines said the planes would be back in the air after safety checks, though it was unclear how soon that would be. There were, for now, no plans to review their use of Boeing’s new jet, the airlines said.

The U.S. authorities have also voiced concern about problems the Dreamliner has faced but endorsed it as a safe airplane. Last week, the Federal Aviation Administration ordered a comprehensive review of the Dreamliner’s manufacturing and design, with a special focus on the plane’s electrical systems. But in a news conference last Thursday, the transportation secretary, Ray LaHood, made no mention of grounding Dreamliners.

Still, the review is unusual, just 15 months after the Dreamliner entered service following a lengthy certification process by the F.A.A. It comes amid a formal investigation by the U.S. National Transportation Safety Board of what caused a battery fire on a Japan Airlines plane that flew to Boston from Tokyo last week.

The safety board said it was “currently in the process of gathering information about the B-787 emergency landing in Japan earlier today.”

Eight airlines now fly the Dreamliner: All Nippon Airways and Japan Airlines in Japan own 24 of the 50 delivered by Boeing since November 2011. The other operators are Air India, Ethiopian Airlines, LAN Airlines of Chile, LOT of Poland, Qatar Airways and United Airlines of the United States.

Boeing has sought to ease concerns about the plane’s design and reliability, and has insisted it was no more trouble-prone than other new commercial airplane programs. Boeing officials said Wednesday they had no comment on the Japanese groundings.

Updesh Kapur, spokesman for Qatar Airways, reiterated Wednesday the airline’s view that the Dreamliner was safe but declined to comment on the decisions by the Japanese carriers. Qatar Airways operates three Dreamliners and has orders and purchase options for 57 more.
