Nigel Wettenhall out at Deni was operating one for a while. I dont think he still has it. It was one of the VH-SS rego'd (i think)
SSL is still registered to him. There are 11 others on the register: IAU; KGX; LDQ; MKS; NGX; OGX; OVC; SSD; SSM; SSV; & WGX.
I can remember one of Opal Air's landing with one engine inoperable at Leigh Creek sometime in the 80's while flight service was still there. Pilot never told them he had one out, just landed, taxied in, parked it up & shut down. It sat there for some time befor another engine was brought over & fitted.
