One of the scariest landings I've ever been a passenger on. I thought the Fokker was a goner. Have been in and out a few times, there was a MAF(?) 206 parked undercover when I was there last. There's an outfit called Niugini Helicopters who operate out of Kimbe, they might be able to help you with some information and possibly broker a security company to guard your pride and joy(most likely with AK47's and Alsatians). You may find that it would be a surprisingly cheap exercise compared to flying back to Moresby to hangar it.
If that fails, PM me and I will get in touch with a few contacts and see if they can help out. Lukim yu!
