I'd be surprised. I worked on the RAF Dominies in the 80s and I reckon they did well to last just over 40 years. I'm sure there are finite lives in terms of Fatigue Index and Pressurisation cycles but I forget what they are. Otherwise, I'd guess that it is corrosion which would usually be the problem, and if you want you can carry on replacing bits after it ceases to be cost effective!
