Yeah, let me see... The manufacturer made a seat well over 50 years ago
and has had no input to how that seat was maintained or modified...
Sure, we could sue them! Now would you have to find the actual
manufacturer that made the plane at the time or the present owner of the
type certificate as it has passed hands a number of time since. Of
course I've never heard of a Navion having a slide out problem (I'm
lucky if I can get mine to move).

Let's face it, if you don't maintain things and/or set them properly
they aren't going to work. I would bet the pin on the seat assembly
wasn't fitted into the hole properly.
