Come on UFO, "is that thing airworthy" is a pretty antagonistic troll like remark. I'm guessing by your posts you are one of the the guys based in Cloudbreak flying Chieftains for OzWest or whatever it's called these days. My point being is that you are actually a pilot and not a tosser troll that's come to pprune to stir the pot. You should know as well as anybody else the all aircraft go tech sometimes. As Chadzat said there is only one in the fleet so it's pretty obvious when an aircraft change has to be made. I'm just wondering where you've got your info from about the number of break downs FNP has had, because from what I've heard it's been a very reliable aircraft. If you've got a figure of the number of times it's gone tech and not been able to depart I'd be very interested to compare this to all the other older aircraft based out of Perth and the newer ones for that matter.
