FAA Grounds 787s

[Cool Guys]

Hi CGB,

The document referred to is here:

http://www.gpo.gov/fdsys/pkg/FR-2007...df/E7-8186.pdf

See the "Proposed Special Conditions" on page 2.

Where Boeing/FAA screwed up is explanied in a few recent releases. The following artical by Flightglobal explains it quite well.

NTSB hearing on 787 batteries reveals Boeing shift on testing

Basically the LI battery installation was supposed to preclude any explosion, release of harmful gases etc but the testing performed did not represent real failure modes and hence the battery installation system was not designed for real failures. Note: The "battery installation" includes the containment structure.

Disclaimer. I am not an expert in the 787 battery system. I am only going by public documents and official releases. Im happy to be corrected by further documents but armchair experts with generalised criticisms will be ignored.

Thanks DB39.

This is a better reference than the ones I provided.

Thanks Danny Boy

I just read the PDF AD. It's logical and makes total sense to me. Hopefully the cost(s) to effect this AD will be borne by Boeing. (Or perhaps jointly with the battery manufacturer).

It is for now a fairly advanced plane that will one day be consigned to history like the former "stars" 727 and DC-9.

As will, eventually, every aircraft that's ever been built ...

Thanks Toffeez, good one!

Aviation Herald mentions that an Ethiopian Airlines 787 flew for the first time yesterday after the worldwide grounding earlier in the year. Can anyone confirm?

Accident: ANA B788 near Takamatsu on Jan 16th 2013, battery problem and burning smell on board

How much confirmation do you seek? BBC News - Boeing 787 Dreamliner returns to service in Ethiopia flight

Preferably from PIC of the flight, but if not, then I guess the BBC is a pretty reliable source as well ... Great to see it's back in the air again

[BOAC]

Preferably from PIC of the flight

we'll ask him to contact you.

ANA will do 200 flights with cargo only, and have temp monitors in the battery case that report on-board and to the ground.

Do they have attorneys in Ethiopia?

Unlikely, as the Yuasa LVP65 cell has been around for over eight years now and seems to work fine in other applications.

Be sure to stay away from the Airbus A350 as well, lasernigel, since it also uses CFRP for it's fuselage.

You might also want to stay away from the Airbus A380, since it has more CFRP in it by weight than the 787 and A350. It also uses a fair bit of composite-laminate (GLARE) in the upper fuselage.

He probably should take the trains or the busses......much safer.

All I'm trying to ask is a sensible question. What is Boeing's and now for that matter Airbus's SOP if a ground handling accident happens. How do you inspect carbon fiber for damage at an airport?

Flown in most aircraft and still do, and have high respect for pilots and maintenance staff. So the sarcasm isn't really warranted.

Qatar Starts

FWIW Qatar is resuming 787 flights, with a DXB - DOH flight tomorrow (Wed).

What's that, about 250 miles? doubt if that qualifies as etops then still won't fly on one, yet

The engineers have a device called a Ramp Damage Checker. It is an ultrasound device, very simple to use, and will indicate to a line engineer whether or not specialist investigation is required.

Thank you Pub User, much appreciated. All I wanted was an answer to a question. Some people don't understand that.
