Turks are Europeans but Turkey isn't part of Europe.
If it was the fault of the pilot, what if he turns out to be an Englishman?

He's still working for a Turkish airline, and the problem is in the management
of the airline and the culture of aviation, not in individual pilots. An
incompetent airline could hire incompetent English pilots just as easily as it
could hire incompetent Turkish pilots.

Or American? And how poor does a safety record need to be before a French
airport won't allow you to use their facility?

I believe French airports largely go with the European Union, which has banned
quite a number of airlines, including most African airlines and some airlines
in Asia.
