I will buy the "all airplanes have an experation date" statement but not because they all get crashed. That is just simply not true at all.Many airplanes get retired when it starts to get raggy or the owner just puts it on a shelf to fly something else. I have given away 4 airplanes now and traded 2 others, one of them a trainer that is over 25 years old and going to be flown by another new student pilot in the next couple of weeks.
We have had one crash at our field so far this year and that airplane is repairable.
