Re: De Havilland to "Pause" Q400 production, future uncertain

I'm thinking it would be the same on the 300 as it has the same engines as the 200. Are you thinking longerons rather than frames? I've seen the longerons replaced on the 300 and it's easily done during a "C" check. It's a bit of surgery and a lot of rivets, I'll give you that.
