For the past few years I have had my License Validated for use in South Africa. It did require me to do the Air Law Exam. Consider you need to study or you will be like me. It was so much fun I had to do it twice. Everything you do with the CAA in SA has a fee. Not ridiculous but a fee. If you validate your license there I suggest a fresh FAA Medical as the validation is based on the longevity of that piece of paper. On your first validation it will also take a week or so as the CAA, contacts the FAA to certify that your FAA license is valid. Ironically there are a few running around Africa with phoney licenses.
New rules are in the mill wheras you may in the future only be allowed to validate your license one time in SA. Not in place yet but due to happen..
If that occurs you should also add a book to your library. "How to validate my license repeatedly through bribery" One thing about Africa is Money talks.., lots of Money sings songs. Now that SA is in transition (Translation= Whites not wanted) anything can be purchased if youre willing to pay for it.
