I have managed to track the Mission Aviation Fellowship (MAF) Chief Pilot and Operations Manager for Kenya and South Sudan, who might be worth contacting. He is experienced in operations on PC12 and C206 in South Sudan and Kenya out of small landing strips. His name Ryan Cuthel and possibly an Aussie. As he is familiar with the region, I wondered if he might be able to help, such as getting the spares to Maurice, transporting Maurice somewhere, and assisting Maurice with the paperwork. As MAF is highly regarded in this region, I suspect Ryan Cuthel may be able to smooth things over with the authorities.
The problem is I do not have Ryan's e-mail, so I wondered if someone who is on linkedin (Terry?) could contact him. Below is his Linkedin page
