I think at this stage to make a link with aircraft type and age with the facts as they are currently known makes no sense.
Of course. It wasn't a mechanical failure, but nonetheless, in last few years polish VIP aircrafts broke few times (I can remember from the top of my head that in one of them engine ccaught fire -- not flameout), so they were not as safe as new planes (and of course I'm aware, that new planes can break too).
