A team of experts from?US aviation authorities and Boeing have?arrived in Japan to inspect a 787 Dreamliner passenger?plane that made an?emergency landing on a domestic All Nippon Airways' flight.
The incident prompted regulators in the US and?around the world to ground the 50 Dreamliners already in?service.?
The Japanese plane?is being?investigated after warning lights indicated a battery problem on?the ANA flight on Wednesday.
The 787, a lightweight, mainly carbon-composite aircraft,?has been plagued by mishaps, raising concerns over its use of?lithium-ion batteries.
The five representatives from the US National?Transportation Safety Board, Federal Aviation?Administration and Boeing are helping Japanese authorities?in the investigation of the aircraft, which remains parked at?the side of Takamatsu airport in the west of the country.
The Japan Transport Safety Board (JTSB) aims to end its?initial checks by around midday on Saturday, a person familiar
with the matter told Reuters, and will make further decisions?based on how the investigations go on Friday.
'Vilified'
GS Yuasa Corp, the Japanese company that makes?batteries for the Dreamliner, said it has?also sent three engineers?to Takamatsu to help the investigation.

A person at the company, who asked not to be named due to?the sensitivity of the issue, said: "Our company's battery has?been vilified for now, but it only functions as part of a whole?system.
"So we're trying to find out exactly where there was a?problem within the system."
Meanwhile Australia's Qantas Airways said on Friday it had cancelled an order for one of 15 Boeing 787-8 Dreamliners earmarked for its budget arm Jetstar.
The decision to cancel the order was reached at the end?of 2012, Qantas said in a statement, before?the string of recent?problems with the aircraft that culminated in the grounding of?the Dreamliner fleet.
Poland's airline LOT said it may seek compensation?from Boeing for the grounding of its two 787 Dreamliner planes.
LOT said both its Dreamliners are safe to fly, but kept them?grounded in?Chicago and Warsaw after flight safety?authorities banned all Dreamliners from flying.
Tomasz Balcerzak, LOT's deputy president,?said on?Thursday that?the airline is?counting costs incurred by the idling of the planes and in due time will?complain to Boeing. He stressed the problems are not the fault of the?airline.
Huge costs
Meanwhile, Japan's transport ministry said a fuel?leak on a Japan Airlines (JAL)-operated 787 last week was due to a malfunction in?a drive mechanism that controls a valve.
It said the British?company that makes the valve was investigating the problem. The ministry?declined to name the firm.
Keeping the 787s on the ground could cost ANA alone more?than $1.1m a day, Mizuho Securities calculated, noting?the Dreamliner was key to the airline's growth strategy.
JAL has cancelled?eight Dreamliner flights on its Tokyo-San?Diego route until January 25, affecting?about 1,290 passengers, and?is switching aircraft for another 70 flights scheduled to fly?the 787.
The JTSB has said the battery on the ANA flight that made?the emergency landing was blackened and carbonised, had a bulge?in the middle, and weighed 5kg less than normal.?
The use of new battery technology is among the cost-saving?features of the 787, which Boeing says burns 20 percent less?fuel than rival jetliners using older technology.
The plane?represents a leap in aircraft design, but the project has been?plagued by cost overruns and years of delays.
