Yes. Engineers do a lot of calculations and the parts are replaced on schedules.

I remember an episode of "Air Crash Investigation" where the repairers fitted two rows of rivets where there should have been three. The repair still handled thousands of pressurisation cycles until it failed catastrophically. Engineers calculated the expected life of the faulty repair and were out by twelve cycles from what actually happened.

They use titanium in critical parts and increasingly, carbon fibre parts glued together. I do hope it is very good glue.
