Investigators are looking into by Honeywell International Inc. (HON.N) emergency locator transmitter built-in battery fires whether Boeing (BA.N) Dreamliner in London last week, according to a source with the probe.
Passengers and investors the message that appears on their pace, for the airlines continue to fly in the U.S. company's shares last Friday plane and regained what they lost on Monday closed up 3.7% $ 105.66.
Honeywell said it has added to Friday's fire aboard the 787 parked at Heathrow investigation, but declined to give details, except to say that it no previous experience, this type of transmitter difficulties.
Boeing declined to comment on the transmitter.
In 2009, the U.S. Federal Aviation Administration (FAA) told Airlines, Honeywell transmitter has failed in the test, and advised them to replace it, and other global regulatory agencies issued a similar announcement. The fire hazard from the unit without any sign.
Honeywell says it is to check whether the Ethiopian Airlines jet transmitter ETHA.UL cited as a regulator of the same model in 2009.
787 transmitter is located in the rear fuselage section, the fire from the "theoretically possible," who has been a consultant, the FAA at MIT aeronautics professor John Hansman said.
But Hansmann said, it seems unlikely that the unit has failed, it is at least possible that a passenger sneaked cigarette smoldering in the bathroom for a few hours, and that the aircraft stands at Heathrow parked in front of fire .
UK Air Accidents Investigation Branch (AAIB), which is leading the probe into the fire, on Saturday said it found no evidence that fire was caused by a lithium-ion battery, grounded implicated in the 787 earlier this year.
Two battery packs overheating provide backup power plane in January caused a ground plane three regulatory bodies and causing the whole fleet renovation and delivery delays.
New technologies plane
Still, some analysts believe, they say, more technical issues, high-tech and new aircraft will haunt focus on EPIRB sounded the alarm.
And Virginia Teal Group aviation consultant Richard Aboulafia said, "unless the company can be said for sure that this incident is isolated to this particular aircraft, this is not welcome news."
"A system problems plaguing Dreamliner is its technology there are so many new regulations to fully grasp all the changes, it is very difficult," he said.
Boeing will resume only after the delivery of the aircraft in May, the plane's lithium-ion battery fire, another overheating, need to re-design of the battery system and more than 50 aircraft modification.
AAIB may take several days, if not weeks to determine the cause of the latest fire, although the source familiar with the investigation said preliminary reports this week that may arise.
Investigators are studying emergency locator transmitter, or ELT, positioned at the rear of the new airliner sent a signal, causing rescue workers downed aircraft, the source said, who was not authorized to speak records.
Another source of Ultralife's battery power supplier, Honeywell ELT Corporation (ULBI.O). Newark, New Ultralife company had no immediate comment.
Lithium manganese
U.S. aviation safety officials say this is the first time they remember such a launch aircraft fire being investigated as possible causes.
Emergency transmitter is powered by a non-rechargeable lithium - manganese batteries. In fact, it is not equipped with a lithium-ion battery can allay the problem re-occurs, leading to the grounding of the earlier concerns.
Lithium - Manganese batteries can be found in some flashlights, digital cameras, and military applications.
Honeywell said on Monday that the Federal Aviation Administration certified ELT has been since 2005, among the many types of aircraft, "We have never seen or experienced a single product line" reporting.
The company said it is involved in investigating the cause of the fire jacket plane, leaving visible scorch marks still too early to draw conclusions. Fire occurred in an area is also located hot water boilers and heaters and other kitchen equipment.
"This is a guess the reason is too early to draw conclusions, said:" Honeywell spokesman Nathan Drevna's.
Honeywell says it has sent technical experts to London to assist in the investigation, and with Boeing and the U.S. National Transportation Safety Board will continue to work closely.
Honeywell's shares edged down slightly on Monday, closing 7 cents to close at $ 82.30.
Tickets, order does not affect the
Analysts remain cautious.
"Any more information on the electronic properties of a human error, Gursky said:" Jason, Citigroup analyst in San Francisco.
"Gursky said:" The most important thing is to remember that from the impact point of view, this is a systemic problem, or assembly bad, or a bad part, or someone left the coffee pot,
UK AAIB said on Saturday that it did not find any evidence of fire was caused by Boeing 787 aircraft lithium-ion batteries, have been implicated in the ground earlier this year.
A 25-strong team of experts, including from the AAIB and NTSB inspector to investigate the damaged Dreamliner in the hangar at Heathrow Airport, about 15 miles west of central London. FAA and Boeing also assist in the investigation.
Airlines, Ethiopian Airlines, British Thomson Airways (TT.L), the U.S. carrier Continental (UAL.N), Poland LOT LOT.UL, representation, they will continue to fly the aircraft of their dreams, while other countries such as Virgin VA. UL said they would stick to their plans to buy aircraft.
"Personally, I would fly to a dream of tomorrow - and said:" I do not think this is a problem, the whole team is like a battery problem is clearly an aerospace analyst Howard Wheeldon, in Whedon strategic consulting.
"I expect AAIB know what caused the fire and the Ethiopian Airlines Boeing end of the week, but the question is 'flat repair'?"
