A friend of mine in Russia works for a small aircraft manufacturer (gliders and motogliders) http://glider.ru/
They are trying to start exporting their gliders into the US again as kits. The previous owners sold over a 100 motogliders to the US before the company bankrupted in 2005.
So now they are trying to figure out all the paperwork needed.
They are looking to export either a ready to fly aircraft or as a kit (90%/70%/49%).

So if anyone can point me in the right direction of where to find relevant FAA documentation I would appreciate it.
