      I am not a pilot but have heard of the term TSO.  I have heard of
parts or equipment that musrt be TSO'd before it can be used in an aircraft.
Just what is this all about?    Also, I understand that if any little nut or
bolt breaks just about anywhere on an aircraft that it must be replaced with
an original one from the factory or one that is aircraft approved or
something like that.  Does this apply to all hardware on the craft?  If you
lose a couple of dashboard screws, can't you just run down to the local
hardware store and get a 100 pak of sheet metal screws?  How stringent are
these requirements and who watches this stuff for violations?
