It is not just the seats, it is about reconfiguring plumbing, toilets, galleys and probably some cabling as each airline is using a configuration specific it.

Punitive tariffs are against the EU in general, so the US can pick any products they choose to impose tariffs. As the US is imposing tarif...

The problem as I see it is that this was not the final test of the static test program. In other words, they have to repair the fuselage, calculate what effects the repaired fuselage has to the rest of the test program, and continue static tests after that. I am sure that they are able to do that, t...
