Not sure if you refer to the audit, the ban or the BEE (Black Economic empowerment)
An audit establish if an organization is performing and/or adhering to certain standards. In the case of the FAA versus the SACAA, the FAA is not happy with the standards of the SACAA which is the government body controlling aviation in SA. So they can decide to ban SA aircraft from flying into the USA despite the fact that individual companies have very high standards through policing themselves. In this case the FAA has given the SACAA time to correct the problem before they will do another audit to see if the problems have been corrected. Otherwise a ban will follow.
If you refer to BEE. Yes. That is law. Blacks take preference over whites, even if the white person is better qualified. Thousands of competent white people have lost their jobs here to unqualified black people. That is the main cause of the demise of the SACAA.
