British Airways investigators found an EPIRB, Honeywell International Inc. last week by the fire in the Boeing 787 as a possible source, and ask it off, Boeing shares rebound spurred relieved investors.
Concerned about the carbon fiber composite jet comeback soon, however, a possible fuel pump failure, Japan Airlines 787 back to Boston Logan Airport.
Federal Aviation Administration spokesman said the incident was not an emergency, but in after-hours trade nervous investors sent Boeing shares fell 1.5%. Japan Airlines spokesman said Naoki Iizuka, the pilot decided to turn back, "as a precaution."
787 program has been beset by problems, since January, lithium-ion backup battery overheating after the grounding of aircraft.
British officials said the fire stopped Ethiopian Airlines unrelated incident at Heathrow in January. Air Accident Investigation Bureau (AAIB) said that a locator beacon and lithium-based batteries near fire on the plane is the only device that has the ability to start it, and called for regulatory authorities review the use of these beacons.
Boeing said locator beacons is not required by the U.S. Federal Aviation Administration regulations, although some other countries enforce their use. The aircraft maker said it would remove its latest aircraft models.
"Emergency locator transmitter does not need to aircraft design part, said:" There is no requirement operated ELT 787 Boeing flight test during the spokesman Marc Birtel.
Beacon device (ELT), also known as emergency locator transmitters are used non-rechargeable, lithium manganese batteries are used in products for decades, such as digital cameras, radios and heart pacemakers.
No rapid removal
Now, the airline will continue to fly their emergency beacons place until FAA instructing them to do otherwise. With most of the big aircraft close surveillance radar and other means rescuers find downed aircraft beacon, most parts of the world, are not critical to flight safety.
AAIB has left the FAA decided to remove the beacon that Japan's Civil Aviation Authority (JCAB) officials.
"Things will not move forward until the FAA decision," he said, down was identified as he was not authorized to speak to the media.
Japan's All Nippon Airways, has 68 Dreamliners currently operates 20, which means that it would await JCAB instructions.
In Washington, the U.S. Federal Aviation Administration says it is reviewing the report, which pointed out that the lack of space in the cabin above the fire detection or suppression said, "This incident occurred in flight, it may bring significant safety issues."
Rain in the plane
AAIB said that it is unclear whether the fire onboard Ethiopian aircraft beacon battery or some external forces - such as electrical short circuit caused the failure - say, the probe will continue.
Although the report focuses on the UK by the United States a beacon of Honeywell Group, aviation experts say, 787 high humidity, which helps make passengers more comfortable, it may be a problem. Water can be conductive, so that a high water content may increase the possibility of short circuiting.
"Investigators are everything, humidity, condensation ... thing is how to install it," an industry source said.
They are checking whether there is enough insulation from condensation, damp and prevent short-circuiting the system, such as beacon, the source said, who was 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 industry insiders refer to as "Rain on the plane."
"This finding suggests that there is any lack of security and the plane, but on the other there is no conclusive evidence unrelated to the plane of the system is to blame," said Virginia Teal Group aviation consultant Richard Aboulafia .
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.
HONEYWELL
Honeywell committed to helping Boeing and airline needs, but warned that too early to jump to conclusions fire. It said it did not expect to act on the recommendations AAIB any financial impact.
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."
Battery Fire of London series by Newark, New Ultralife Company, 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."

UK AAIB investigation, said last week's fire was an accident in January grounded 787 advanced carbon fiber composite aircraft nothing more than three months.
Investigators have not determined what prompted these cases involved a battery melt down. Boeing solved this problem by packing fireproof steel box on the battery, in the plane and cutting any overheating of the battery vent dumping smoke in the future.
Fuel pump warning day (Thursday) JAL flight from Boston melted battery or emergency beacons unrelated, the carrier said.
JAL said 184 passengers on board flights bound for Tokyo JL007, got about three hours after leaving Boston fuel pump maintenance information. Plane landed safely at the airport the afternoon 6:16 (2216 GMT), and there was no sign of smoke, it added.
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. Honeywell's shares rose 0.6 percent on Thursday to close at $ 82.97.
In Tokyo morning trade, JAL shares fell 0.9 percent, unchanged from yesterday's close with the ANA and, while in the benchmark Nikkei 225 index fell 1.1%.
