Hiya,
Indeed, i used to work for them in CAR also.
Bangui is not a bad town except when a coup is in place...some good restaurants, cafes and you can buy pretty much anything in the shops.
The only problem is electricity and water sometimes. As well as the local police and army can be a bit demanding, especially on friday and saturday nights...
Enjoy!
On the job aspects, if you are L410 rated with some hours, you have a pretty much straight and paved road into Air-Tec.
Cheers,
booze
