There’s heavy licensing when it comes to aviation. You can’t buy Boeing parts on ebay sold by chinese vendors and install it on aircraft. At least yet.

  ... well, you can. Sometimes it even involves purser walking cap in hand scrounging up cash for a fuel pump replacement in pretty young 787 otherwise it's not going anywhere. The main difference is that it's tracked. Licensed, too, but huge part of that licensing is about maintaining the history of the parts and plane, and that mechanics know given plane. But the only reason you're going to know that a change happened was because the people have been trained to log it down - but there's no physical/computer lockout preventing them.
