Choosing a spec and sticking to it
I'd be happy if ALL contractors could push out stuff that complied with Def Stan 00-970. No, really comply, even if it was to the predecessor (Av P 970?). Make a good aircraft that crews would be happy to fly, engineers could be proud to have worked on and everyone who actually knew anything about aircraft in general and that one in particular would look at and say "Now THERE's an aircraft they got right..." I challenge anybody to name one. Great to fly/operate but a sod to maintain, or vice versa, doesn't count.
