All in all, the various Viscounts had a pretty terrible record in Australia.
I don't know about that Leddie. The RAAF flew two Viscount 832's for a couple of years and as far as I recall we had no problems with them. They were a delight to fly and the soft undercarriage made greasers out of landings that in other types would be hard. The RR Darts were very reliable and I don't recall any in-flight shut down due engine malfunction. Not like the RAAF Convair 440 Metropolitan, where we had engine failures, engine start-up fires and a spate of un-commanded in-flight featherings and in one memorable case a runway propeller after lift off at Canberra.
