Howdy,

How does FAA type certification relate to intellectual property
rights? For example: everything in an O-235 has been out of patent for
years now. Same with old aircraft designs. Is there any reason why
somebody couldn't tool up and start ripping out O-235s, and selling
them new?

I notice that I can buy cylinders for my engine from several sources,
all with FAA blessing. Could the same legal techniques be scaled up to
a whole engine, or a whole airplane?
