Here we go again...
The PC-12 has now been operated in Aus for more than 15 years, the fleet is of a very respectable size, and it flies a very large number of hours each year.
If the afore-mentioned incident in WA is the worst thing that has happened in that time, that's a pretty good record.
(An incident that would certainly get your attention, but hardly the stuff of nightmares)
Now, how many King Air accidents have there been in the same time frame (15 years+)?
Oh, and the ambo's in SA (SAAS) routinely fly in RFDS PC-12's. I guess they're not as soft as their VIC counterparts (or perhaps not as poorly informed?)
