VLAF,
Lolita is right, historically CAA Cameroun has threatened (and acted on) closing down Schreiner/CHCs AOC a few times, same same for the Schreiner/CHC Tchadian AOC by CAA Tchad, for various reasons.
In each case the aircraft were moved to the other country until negotiations were paid up again, er, conformity was re-established.
What a circus.
More disturbing about the post is the geography... N'Djamena-Douala Twotter operations normally stop in halfway point and international airport N'Gaoundere is to clear customs and take fuel. A direct flight is possibly under the right conditions with much lower loads, but trip burn is usually a little shy of tank capacity.
The only reason to fly through Dompta and/or Belabo on these runs (apart from N'Goundere not being available for any reason in which case Ngoundal is always there) is an urgent commercial (client) requirement because it is way off-track for N'Djamena-Douala but right on-track for Kome/Moundou-Douala.
Whatever.
Maybe they should look for proper dispatchers

p.s.: who's the trolley dolley?
