You got it all wrong, NTSB has no power to charge Korean pilots (or any other pilots) with anything, their role is to investigate accidents, write reports and suggest remedies, if anybody wants to charge these pilots it would have to be somebody in Korea. Since this was a foreign crew they could not even take their blood samples. Criminal prosecution of pilots after accidents is quite rare. In the US you would have to prove not just a negligence but 'criminal negligence', basic incompetence is not grounds (in the US) for criminal prosecution.
