Mmmh...
Have a look for Aeromarine, they operate all sorts of SEP and MEP, and do also operate a Beech 99, and an Aerospatiale Corvette (yes, theese things still exits), all of these out of Tana (Antananarivo).
I must warn you, the economy in Madagascar is one of the lowest in the whole "African Continent"...no need to tell you more, right?
So IF you go there, good luck if you get a Job. I'm sure it's possible, but far to be easy. And of course, in Mada, you NEED to be fluent in french. Awsome country, Awsome people, but not much Aviation left down there.
