I read that article a couple of weeks ago. I've concluded that dealing with manufacturers who can designate who can and cannot work on the planes they built would be a boondoggle worse than dealing with the FAA.
So, should I decide to fly under a sport pilot license (in my case all I need to do is not renew my medical and be certain I have a valid driver's license -- no need to take sport pilot training because I already have a PPL; I could even fly into towered airports without a new CFI sign-off because that was covered by the instructor when I got the PPL), then (boy, this is turning into a long sentence) . . .
Then I would only purchase a certified aircraft that meets the light sport airplane rules OR buy or build a homebuilt that meets the rules.
