Scrapped Parts Sales

How are scrapped parts sold?
What kind of airworthiness directives govern them?
What kind(s) of documentation comes with them?
What checks need or need not be done on these parts?
What parts cannot be sold?
Etc, etc, etc...
Any insight into the used parts market would be appreciated.

MD-11 winglets are quite particular because they have a smaller "winglet" below the wing's center line. (I'm no aircraft designer, so bear with me if I'm calling this thing the wrong name). No other commercial aircraft has this. Airbus planes have something like it, but the configuration is very dif...
