Iso,
Are you asking about their fixed wing or rotary wing operations?
They have 4 Dash 8s and a few Twin Otters based in Lagos and are not downsizing as they now have a licence to operate scheduled services between Lagos, Warri, Port Harcourt and Abuja. They don't have many expat pilots on fixed wing any more though. One thing to be aware of in Lagos is the number of armed robberies, which is on the increase. The ACN staff house in Lagos was hit by armed robbers 5 times last year!
They need pilots for their rotary wing operations, having a fleet of 2 AS355s, 2 S76B, 1 S76C+, 1 SA 365C2, 3 SA 365N2 and 5 SA365N. All but the Twin Stars are based in Port Harcourt and the majority of the flying is 2 crew oil support operations to flow stations in the swamps and to platforms and rigs offshore. The accommodation in Port Harcourt is very basic, though being improved. There are not as many armed robberies there, but there is always the possibility of being hijacked as has happened to numerous Bristow and ACN helicopters. Communication (or rather the lack of) with the outside world is pretty dreadful, though they are trying to set up some kind of satellite internet access for e-mails from guys laptops.
If you want any more info just send me an e-mail.
