I’m going to try to research the age of aircraft in all crashes over the last 10 yrs. Will get back to you.

Yes, sometimes age is a factor, but, also, how well the plane is maintained.
Many plane crashes are caused by weather, pilot error, ATC error.
If a plane of a good run airline is well maintained and they don't cut corners, then they are safe.
