I think you will find ARCWI is right. Even before the KOX accident, Zambia DCA had stepped in to prevent ZS light aircraft (C206,C210 etc) being leased in to operate in Zambia on a commercial basis. We were only allowed to bring a ZS light aircraft in on the basis that it was a temporary replacement for a similar 9J aircraft that was down for maintenace for a couple of months (August 2004). After KOX I think that even that allowance was banned.
But drop an email to DCA Zambia to re check.(

I will be back in Lusaka in a couple of weeks and can check as well. Send me an email.
