Nighttime Ban on Airports in DRC

Hej,

As you maybe know from my self-introduction, I am interested in the DRC's aviation :)

So, it would be interesting for me to know if there is such a nighttime ban on some airports in the DRC. Here in Europe we have that on nearly every airport... And I can say it isn't really good for the airports economy. But for the people living around... Yeah, you see, great stuff for are debate :D

But back to my question. I don't think that Kinshasas N'Djili has a nighttime ban, but I am thinking about the airports in the east, or north-east. There is very little information in the web about that... So, what about Goma, Buta or Kisangani?

I hope someone has some information for me, or some interesting links ;)

Thank you!
