Incidentally, Airbus outsources majority of it's work. Heck, whole Airbus entity is one giant outsourcing hairball.
Personally, I believe that outsourcing is OK (albeit risky) as long as you know how to set deadlines and have clear QC-parameters.
It's somewhat blown out of proportions IMHO. They'l change all batteries to NiCd, loose a few pounds and that's it.

P.S. A380 uses LIon batteries as well, but only for emergency lights.
This is correct. With the fire potential on the Li-Ion batteries, I'm surprised they have as much widespread as they do. Of course, I'm typing on a laptop with Li-Ion batteries inside...

The quick fix will be to replace the Li-Ion batteries with "something else", and to pay the small weight penalty.

I haven't been able to talk to my sister, as she is working 12-16 hours days with the team trying to fix this fast.
