9RG, 9KZ, 9WA, are not flying any more my friend!
We are buying others Delta Airplane's ,in the near future, to replace the other B727s.
Mbuji-Mayi isn't scarry at all! We land there every day!
You're free to come to HBA operation's office to discuss the issue, and check with HBA, our T/O weights for those fields.
