Bit harsh on the piston powered Cheyenne, Gaunty!
One of the selling points for the RFDS on the Mojave was aircraft came standard with cargo door, whereas the C414/421 required the expensive large door modification.
As I said in my previous post the RFDS were desperate to standardize their fleets, so many different sections and so many different ideas. Cessna, Pipers, Beechcraft and GAF, must have been an aircraft salesman dream.
We tried to purchase VH-HFD and its extensive spares package(2 engines, 2 props) off the RFDS WA Section but was pipped at the post when they sold it to the RFDS TAS. The RFDS had done a very nice job of the medical fitout in the Mojave, but at the end of the day 190 kt piston twin isn't suited for the long distance in WA
We spent sometime talking to Airlines and Tasmania who operated VH-XGW on the air ambulance contract and they had a pretty good run with it, but obviuosly spent time and money training their pilots to do everything the right way. The chief engineer sang the praises of getting full engine life, and no major problems.
