British Airways investigation determined by Honeywell International Inc. (NYSE: HON - News) Boeing last week as a possible source of a blaze (NYS: BA - News) 787 and emergency beacon called it off, Boeing shares rebound spurred relieved investors.
Later on Thursday, Japan Airlines <9201.T> 787 back to Boston's Logan Airport after receiving in-flight fuel pump maintenance tips.
Federal Aviation Administration spokesman said the incident was not an emergency, but nervous investors in after-hours trade marks Boeing shares fell 1.5%.
UK Air Accidents Investigation Branch (AAIB) said locator beacon, its battery is the only Ethiopian Airlines planes parked at Heathrow Airport, near the fire source and the power to start the system.
Boeing said that in about an hour, can remove its latest model aircraft grounded more than three months, which is earlier this year in January 2 incident, because the lithium-ion backup battery overheating lighthouse.
Boeing shares closed up 2.7 percent at $ 107.63, the high of $ 108.15 reached close to a week ago in the fire. Boston event, and then see the stock fell $ 106.
AAIB said that the lighthouse is still unclear whether lithium manganese battery or some external forces - such as fires caused by electrical short circuit fault is - say, the probe will continue.
In its report, AAIB also called on the U.S. Federal Aviation Administration (FAA) and other regulatory agencies to review other emergency beacons used by all other aircraft using a lithium-based batteries.
British officials said last week, grounded 787 unrelated events fire in January. Investigators never determined what prompted these cases involved a battery melt down, but Boeing fireproof box they come in, solve problems, and find a way to vent any plane may cause a fire.
There is no indication in Japan Airlines plane back to Boston anyway, even past events involving dreams, but it emphasizes the cautious, now surrounded by high-tech aircraft.
"The pilot decided to turn back a rich cautious," Boston Logan International Airport spokesman Richard Walsh told Reuters reporters.
Carol Anderson, JL007 flight on board 184 passengers bound for Tokyo, Japan Airlines spokesman said, about three hours after leaving Boston got the fuel pump maintenance information.
Anderson said, as a standard precaution, the aircraft returned to Boston, landed safely at the airport at 18:16 (2216 GMT), and there is no sign of smoke.
This is a fire in a parked Japan Airlines 787 in Boston early in January stranded Dreamliner, an aircraft that combines lightweight composite parts and a new electrical system, in order to achieve its fuel efficiency and help lead.
High humidity
Although the report focuses on the UK by the United States a beacon of Honeywell Group, aviation experts say, 787 high humidity or other environmental factors may also be problematic. Water can be conductive, so that a high water content may increase the possibility of short circuiting.
"Researchers are looking for everything, humidity, condensation ... how things are installed, which is a comprehensive effort," one industry source said.
Boeing's new aircraft has a relatively high humidity, which helps make passengers more comfortable, and the investigation is now to find out whether there is sufficient insulation to prevent moisture condensation and short-loop systems, such as beacon, said the source, who is not authorized to speak publicly.
Close to the case, he has not been named, Boeing, an informed source said that 787 might need better isolation from the aircraft electrical components with high humidity, some of the industry refers to as "rain in the plane."
Analysts said they are looking at further development.
Teal Group analyst Richard Aboulafia said: "This finding suggests that the safety of the aircraft did not lack anything, but on the other hand, system-independent plane is to blame, there is no conclusive evidence, . "
Headquartered in Paris, Oddo Securities analyst Yan Derocles consent. "We have to wait for the conclusion, at this point it may be Boeing's a problem, because the inherited 787 events may erode confidence," he said.
Boeing said locator beacons is not required by the U.S. Federal Aviation Administration regulations, although some other countries enforce their use.
AAIB recommended if regulators through 787 carriers will operate their aircraft without a functioning ELT ELT No part of aircraft design. There is no requirement operated ELT 787 flight test period, Boeing spokesman said: "Mark Birtel.
Locator beacons, also known as emergency locator transmitters (ELT) 787 top rear, and may lead to relief workers downed aircraft. They are powered by non-rechargeable, lithium manganese batteries are used in products for decades, such as digital cameras, radios and heart pacemakers.
HONEYWELL
Honeywell said it would help Boeing and airlines need, but cautioned that the fire jump to conclusions too early. It said it did not expect to act on the recommendations AAIB any financial impact.
Honeywell's shares rose 0.6 percent on Thursday to close at $ 82.97.
AAIB report said the fire occurred in the 787 ELT equipment are located in the upper part of the rear fuselage. "There is no other aircraft in the vicinity of the system, non-powered aircraft, including the energy stored in the damaged area of ??the head can start a fire," it said.
It is said that no large transport aircraft cabin space above the ceiling fire detection or suppression, "This incident occurred in flight, it may bring significant safety issues."
Boeing said it supports the AAIB's proposal and reiterated its confidence in the safety of the Dreamliner.
In Washington, the FAA said it was reviewing the report.
Battery is connected to the Great Fire of London by the Newark Ultralife Corporation, headquartered in New York, the company (NMQ ULBI - News), according to an industry source. Ultralife Corporation did not respond to calls seeking comment or e-mail. Its shares fell 1.8 percent, to $ 3.76.
AAIB said that Honeywell has produced about 6000 ELTs same design, are fitted to a wide range of aircraft, which is the only significant "thermal event."
In the beacon battery indication "break" AAIB report said. "It is not clear, however, whether the release of energy from the battery, or by an external mechanism such as an electrical short in the region of ELT combustion initiation."
