It's been so long since I crashed anything! I think my last deadly crash was a CAP 19X (Did they have a 190 something?) back in '90. It might have been disorientation, (pilot error) or a radio glitch. I seem to recall losing radio contact, but it might have been me flat spinning it into terra firma.

I'm with those that say "Pilot Error", which would also encompass reversed controls, loose parts, etc. "Pilots" pre- and post-flight their aircraft... Right?

It happens, though. I was teaching my daughter to fly a GP Cub on a box several months ago, and guess what... I had the ailerons going the wrong way on the buddy box! I kept telling her "left on the box!", and she kept going right with the plane! No disaster, but an amusing lesson in failure to pre-flight.
