I think we will see many subcontractors supply to various aircraft OEMS. Spirit (were 737 & 787 noses are build) is bidding to take over some Airbus factories. Alenia will probably build big parts of the 787 and A350XWB.

Quoting SEPilot (Reply 9): What problems have they had? The only pressure dome problem I am aware of was the 747 in Japan that blew because of a faulty repair.
I would say that might be the only one that was a news event. When I started working the 777, one of the first thing the mechanics where telling me. Is when you go up into the 48 section, be extra careful for the pressure dome. They told me that they are easy to damage and not very fun to repair.

That I can believe; I suspect the same may be true for the 787, A350, and most other planes as well. It is a very critical piece in a rather difficult spot. The composite ones may be less easy to damage, however, so that may make your life easier.

Quoting F86sabre (Reply 8): I just hope the dome is much more durable than the ones they put in the 767s and other Boeing aircraft with domes. It will be interesting to see what the SRM will offer in terms of repairs.
The pressure dome gets its strenght from its shape not the thickness of the material. All domed pressure bulkheads are very light weight and easily damaged. However, once they are installed about the only way to damage them is by dragging the tail or allowing it to corrode.
