Regarding the OP about African Airlines it seems that the old flag carrier of Central African Republic "Karinou Airlines", (Karinou after a hero of the 1928 colonial war), lost its AOC last March/April due to Covid, and its now trying to restart Ops based in Brazza under its first/original name "African Airlines" wich dured on the first year of their ops in 2012.
