Dudeness, think the aviation background of the owner is mainly recreational. He likes to fly, enough to have invested in the air taxi company, having the accident aircraft registered with his initials and having built a resort/golf complex accessible mainly by air.
All of which, of course, says nothing about his proficiency, although Brazilian authorities did confirm his license is current. So, in that respect, he's clean. He may, of course, not have been as up to date or trained as crew on regular commercial flights into CGH are. There are no special licences required of crew flying into CGH (yet) as there are for Santos Dumont so, if you can get a slot and have the requisite aircraft licences, you're in.
