Japan grounds Dreamliners
Japan's two main airlines have grounded their Boeing 787 Dreamliners after one was forced to make an emergency landing because of battery problems.
All Nippon Airways (ANA) grounded its fleet of 17 Dreamliners after its flight NH 692 from Yamaguchi Ube was forced to land shortly after takeoff.
Japan Airlines followed suit, saying it would ground its fleet of seven 787s from 16 January until further notice.
This is the latest setback for Boeing and its problem-hit Dreamliner planes.
In recent weeks, Dreamliners have suffered issues including fuel leaks, a cracked cockpit window, brake problems and an electrical fire.
"You're nearing the tipping point where they need to regard this as a serious crisis," said Richard Aboulafia, a senior analyst with the Teal Group in Fairfax, Virginia.
"This is going to change people's perception of the aircraft if they don't act quickly."
Battery malfunction
On Wednesday, ANA's flight NH 692 left Yamaguchi Ube in western Japan at 08:10 local time (23:10 GMT) and headed for Tokyo's Haneda airport.
Shortly after takeoff smoke was seen in the cockpit, but not in the passenger compartment and a strange smell was reported.
Airport authorities were taking no chances with the emergency landing
ANA says that it does not yet know the source of the smoke, and is investigating the problem.
However, it added that the battery in the forward cargo hold was the same type as the one involved in a fire on another Dreamliner at a US airport last week.
The ANA flight landed at Takamatsu airport at 08:47 on Wednesday after the pilot saw an error message in the cockpit.
"There was a battery alert in the cockpit and there was an odd smell detected in the cockpit and cabin, and (the pilot) decided to make an emergency landing," said Osamu Shinobe, an ANA vice president, at a press conference.
ANA said that the 129 passengers and 8 crew were evacuated, with a number of people sustaining minor injuries.
The Reuters news agency reported that five people were injured, while Bloomberg said that one person was sent to hospital. ANA were not immediately available to confirm the figures.
The BBC's correspondent in Tokyo, Rupert Wingfield-Hayes, said that local television footage showed emergency chutes were deployed from the plane. There were also fire trucks on the runway.
Market Reaction
Paul Lewis, a spokesman for Boeing, told the BBC that the planemaker was "aware of the diversion of a 787 operated by ANA to Takamatsu in western Japan".
He added that Boeing "will be working with our customer and the appropriate regulatory agencies".
The concerns have spread beyond Japan, however, not least because the Dreamliner was seen as Boeing's flagship new aeroplane and had attracted orders from many of the world's biggest and best-known airlines.
The 787 is said to be one of the most fuel efficient in the industry, and Boeing delivering 46 Dreamliners to customers in 2012.
Following Wednesday's landing, India's aviation regulator said it would review the Dreamliner's safety and talk to parts makers.
Despite this, the regulator said it had no plans to ground the six Dreamliners that are currently being used by Air India.
Australia's Qantas Airways said its order for 15 Dreamliners remained on track. Its subsidiary Jetstar is due to take delivery of the first of its aircraft in the second half of this year.
United Airlines is the only US carrier currently flying Dreamliners, and the carrier said it was not taking any immediate action.
Closer look
Even before Wednesday's emergency landing, Boeing was facing a probe by Japanese and US authorities over its Dreamliner issues.
Last week, the US Federal Aviation Administration started a broad review of the design, manufacturing and assembly of the Dreamliner.
On Tuesday, Japanese authorities said they would conduct a probe after two successive fuel leaks on a different 787 operated by Japan Airlines.
On 8 January, Japan Airlines reported that a fire broke out on a 787 shortly after it landed in Boston. There have also been reports of brake issues.
"It is not abnormal for new aircraft to have some teething problems," said Chris de Lavigne of Frost and Sullivan in Singapore.
"There were initial issues with the Airbus A380 as well. Look where it is today; it is flying successfully and everyone seems to be happy with it."
However, he added that a lot would depend on the outcome of the two investigations.
"If it turns out to be a major issue and requires re-engineering to be done, then you may need to ground some of the planes or even the entire fleet." BBC
