From this graphic, it could be the region of Crew Rest Area under that position.

Is the rest area location consistent across all variants?

At around 1600ish PIA (777) at T3 had the fire service in attendance did not hear the reason why. So with the airport fire teams at PIA and Ethiopian then no fire cover.

I think the issue with this plane is not only to repair the burn damage but also to have it cleaned from any foam residue.

AFFF is quite nasty stuff which will do quite some damage and it seems that they dozed nearly the whole plane with foam.

Depending on the damage inside the plane I think we could see the first hull loss of the 787...

Laptop battery thermal runaway on the bunk? .

If it is systems related, anyone want to hazard a guess as to how many years before the 787 is granted ETOPS clearance?

Where is the fix located?

Where is the Boeing fix located on the airplane? Is it in that same area as the burned area?

If not, we could be talking an entirely different issue like a galley fire or crew rest area fire....

AFFF is smelly, and corrosive, thought it had disappeared a while back

Absolutely no chance. In the extremely unlikely event of this a/c being beyond economic repair, Boeing would still repair it in order to retain the no hull loss record.

Well lets hope for Boeings sake it isn't a battery issue. But to scorch the outside of the hull it must of got VERY hot inside! We don't know if the cabin is damaged yet.

I don't have a CLG for a 787, but that is in the area Boeing likes to put the ELT, and the aft antenna looks like it could be an ELT antenna.

FWIW: Every time I've ordered a 406 ELT it has to come ground. Something about the battery being haz-mat or a fire danger (lithium)

According to CNN, the aircraft had arrived this morning and was parked to await it's evening departure back to Addis with no crew or passengers on board.

A close-up still from a BBC News video....

That's not just scorching - that's a decent size hole.

I'd wait for the views of the composite experts before saying that...!

Unbelievable!!!!! If I am not mistaken, Ethiopian conducted its own repairs on its 787 fleet and got them into the air the quickest of any airline.
Absolute rubbish!

These weren't 'repairs', they were modifications and were carried out by Boeing, Thales and Securaplane engineers.

Battery located in aft electronics bay wherever that is?
The APU battery is aft, but beneath the main cabin floor. Its doubtful that a fire at that location, reaching the top of the fuselage would do such localized damage.

There are other subsystems with their own batteries, such as emergency lighting. Those are located in various other places, possibly near this damage. But I think its too early to blame a battery yet.

787 SERIES. 787.0.7. AIRPLANE RESCUE AND FIRE FIGHTING INFORMATION

Shows no battery in area of damage, and no flammable materials, but it does match 'OVERHEAD FLIGHT ATTENDANT REST AREA' pretty much exactly.

We should not forget that burnt carbon fibre is dermally toxic!

Its a little odd. No crew or pax on board, I am assuming all systems were off and still something just ignites by itself.....
Lets wait a little to see what it was. They will know pretty soon what coused it.

Below the main cabin but forward of the wing trailing edge, the EEbay's aft bulkhead is the aft cargo bay forward bulkhead - if you see what I mean! So nowhere near the damaged area, we can rule out the APU battery this time I think
