Beany, according to the article only 1% of NTSB accidents are attributable to medical conditions. That's not very much. And that's in total - they could come from only Class 1 holders, for all I know.
At the moment there's heated talk within EASA and all it's sub-committees about the new European LSA standards and if it should require a medical at all. Unsurprisingly, the AME lobby and all the flight medical doctors and associations are vehemently against the fraction that want the new rating to not require a medical (FAA style). Because this is in their financial interest of course. It's not that they care if we drop out of the sky or not, in fact, I don't think they could care less about flight safety. No, they want legislative protectionism and cushy monopoly.
