I agree with RotaryWingB2's suggestion for Africa. You need a simple machine which can carry the pax at temperature and altitude. Does not matter how good the manufacturer support is you have customs amongst many other things to deal with so you do not want to get in a situation where you require too many spares for instance. Custom clearance and work permits for engineers if something goes wrong is a nightmare so unless it's a contract or insurance requirement stick with something requiring minimal maintenance support. The 130 is prooving herself in Africa as a workhorse and of course there is the 350 but the 130 for pax is more than adequate. A twin requires extra maintenance and auto pilots extra 6 monthly or yearly checks so be careful cause those are the undefined potholes!
