So from the previous information might one conclude that the answer to the original question is that aviation in Africa is really, really unsafe?
(Doesn't 5% of the passenger miles and 23% of the accidents makes an aircraft accident/crash possibility 46 times greater on the sub continent than elsewhere and that's only for jet airline carriers?)
One must concede that driving is pretty hazardous throughout Africa but then that's probably because most of the drivers in Africa either don't or shouldn't have licences.
