Yeh, lucky they didn't put PT6's in King Airs.

Josh Cox....could be the beers consumed on days off or not but somewhat confused by your statement.
Can only guess that there is no tongue in cheek smiley.

To (probably) confirm your point.
I am an advocate for sting airs but have never driven a PC12. Therefore a very jaundiced view.
I have had a failure in a PT6 on a sting air and it was essentially just a matter of don't stuff the landing and all will be fine. All was..good for me & pax.

I would state though that the preliminary report just shows the standard of training the driver maintained and showed to deal with the situation. Might have more options in a Be200 but still take my hat off to the lady driving.

Good job that woman!

I think the point is how MANY PT6s they put in the Kingy....

Hi Max,

Was hoping to highlight that the issue was not "PC12", it was "PT6", hardly ammunition for the B200 camp, as the B200 has either 41's or 42's.

Have flown both and will not argue that two engines in an experienced and well trained pilots hands generally offers more options than a single engine turbine, if one had an engine failure.

But, that does not make the single engine turbine unsafe, pointing out that it must be flown differently, always acutely aware of ones glide distance and near by options (when I had the choice between the two I would always take the PC12).

IMHO the PC12's I was flying were far superior for the job than the mighty King Air.

All risk is mitigated by control factors.

Experienced pilots, good maintenance and good training can not be beaten, as can be seen by the outcome of this event.

Cue: Capt Wally MK2.

Outstanding result by the pilot, due good training & obviously a women who can perform well under duress, well done & in a very risky environment that never had to be the case considering there are other safer alternatives/choices as used elsewhere:-)

But I thought that turbine engines never failed.

Imagine (and I know it's Derby but just play along) if the WX had been below MDA. Yikes.

That second old leaky piston donk in a MTOW PA31 is starting to sound pretty good compared to one shiny fan on the nose.

Disclaimer: I'm pretty sure I've just contradicted some pro-PC12 post I've made in the past so please don't waste your time by pointing it out.

An interesting observation from the report:

All of the failure events had occurred after engine overhaul, with no events associated with new production engines.

A No-brainer then..
Just fit factory new engines to the singles come overhaul time, and fit the overhauled ones into multiengine airframes..

Or do the sensible thing and restrict single engine IFR ops to private as per the spirit of the original regulations

That would make for some very cheap buying of PC-12's

Maybe Forkie and I could scrape up enough to buy one each ........and keep scaring Wally!

It always comes back to number of engines in the Beech v Pilatus grudge match!

Now that is a very significant consideration, but there are others...

What about range? (You think there's not many places to go in the Top End that are lit, try the middle of WA!)

Or choose your overhauler very carefully.

Just stop overhauling PT6's in PC12's. That seems to be the problem.

Bushy, with all due respect this problem is hardly confined to PC12 aircraft only. More to do with the PT6 varient. The same failure has occurred in this model of engine in other aircraft also (including other SET types unfortunately).
