Boeing 787 aircraft grounded after battery problem in Japan

BBC's Rupert Wingfield-Hayes: "Warning lights were going off showing there was something wrong"

Japan Airlines has grounded a Boeing 787 Dreamliner aircraft after detecting smoke or gases that may have come from faults with the main battery.

The problem was discovered during routine maintenance, and is a reminder of the battery faults that grounded all 787s for three months last year.

The airline said engineers noticed smoke, and then warning lights flashed signalling a battery fault.

Boeing said it was aware of the issue and is working with Japan Airlines.

The aircraft maker said that early indications suggested that a single battery cell had released gases, and that the warning system had operated as planned.

No passengers were on board.

The company's shares price initially fell 1.5%, but eased backed later.

Any 787 battery problem is a sensitive issue. The worldwide fleet of Dreamliners was grounded last year while investigators looked into why two batteries on separate aircraft overheated in less than two weeks.

Boeing redesigned the battery system, although the precise cause of the problem was never conclusively proved.

Richard Westcott, the BBC's transport correspondent, said: "Boeing says it appears that one cell within the lithium ion battery had gone wrong. The number of cells is highly significant.

"There are eight in total for each battery, and if the chemicals spread from one to the next it can potentially start a fire.

"Boeing never did solve the battery problem that grounded the entire Dreamliner fleet last year. Instead, Boeing put in a raft of safety measures to contain any future issues."

There are 115 Dreamliners currently in service with 16 airlines.

    Guntram Wolff is the director of European think tank Bruegel, and he's on 5 live, talking about Greece. "It was a mistake that Greece joined the euro, but it would now be a mistake for it to leave," he says. "We will have to come to a deal that will have a lower burden on Greece. I essentially think you will keep the nominal amount [owed to bond investors] but you will increase the maturity.. from 30 to 40 or 50 years."

    Ewen Cameron Watt of Blackrock is the markets guest on 5 live, talking about yesterday's results from Shell. "These are very historic results because they reflect an average price of $75" per barrel of oil, he says. Bearing in mind oil is below $50 today, "the pain is yet to come," he adds. The firm has cut $15bn of investments. The longer the price remains at this level, the more likely more investment cuts will come, he says.

    Figures from the National House Building Council show there was a 9% rise in homes built last year to 145,174, but the rise missed the government's 200,000 home target. Peter Vella of Countryside Properties is on 5 live. NHBC's figures don't take into account all homes started or built, so the industry could be closer to the target than thought.
