787 Fire at Heathrow
 

Sounds like Mesa!

No where near the batteries.
Aft galley/lav area.
Not sure if Ethiopia ordered the aft or forward crew rest area.

I've heard that you can have the crew rest area there, but not all airlines choose to do so (very likely that there isn't a crew rest area there).

Our 777's have a F/A crew rest in that location, the Pilot crew rest is up top too but up front, overhead the F/C area. Not sure if some of the 787's have the same layout, but it would not surprise me if that was where the F/A crew rest area is, since it is on the 777.

Might have been a wiring issue with all the reading lights up there. Funny no 777's have had that type of fire...yet...that we know of.

On some of our 767ER's, they have just added a below floor (cargo area) crew rest box, do any of the 787's have that type?

Don't quote me, but I believe Ethiopian does have a crew rest above the aft galley.

CNN is reporting that the Honeywell ELT is the source of the fire. It is always electrically connected.

At Boeing... we build bombs!!

The AAIB statement said: "Detailed examination of the ELT has shown some indications of disruption to the battery cells. It is not clear however whether the combustion in the area of the ELT was initiated by a release of energy within the batteries or by an external mechanism such as an electrical short."

"The Journal, citing a person familiar with the matter, said the AAIB is preparing to ask the U.S. Federal Aviation Administration and the European Aviation Safety Agency to assess the necessity of the devices on 787s.

Officials at the FAA and U.S. National Transportation Safety Board (NTSB), which have both sent representatives to London to assist with the investigation, declined comment, referring queries to the AAIB.

A spokesman for the European Aviation Safety Agency said he had no information on the elements contained in the WSJ report

Honeywell said the report was based on "anonymous speculation" and said its officials had not been contacted by British or U.S. authorities involved in the investigation.

However, spokesman Steve Brecken said Honeywell always puts safety first and "would support an action like this as a precautionary measure if our team, or the AAIB and NTSB, determine it's necessary to do so."

Honeywell says it has built over 3,000 emergency beacons since they were first certified in 2005, and insists that it has not seen or experienced a single reported issue with them.

The FAA did issue a special airworthiness notice in 2009 in which it advised airlines to replace the antenna used by an earlier version of the Honeywell transmitter because it had failed in tests. Other global regulators published similar advisories at the time."

UPDATE 2-Honeywell says would remove 787 beacons if asked as fire probed

3000 of these in service.
