There was a halfhearted attempt recently by the CAA to stop people from getting validations renewed again and again. And guess who got the short end of the stick? Two south african guys working for a local South African airline who both happen to not have SA ATP ( only Comm ) but are using validations of their FAA ATP in order to be in the left seat. They were both told that their validations will not be renewed again and they now have to get SA ATP.
