|  3 caravan crashes within the past 6 months
I heard they are bore scoping all the engines in the field. Does anyone know the reasons for any of these failures?

Well sounds like its true. I rode with a corporate air pilot back to the airport today. He pretty much confirmed all there C-208's are being bore scoped. Two weeks ago they found were the igniters were located numerous cracks on the engine. He was going to have to ferry one for the inspection in the next day or two.

I believe him I'm just wondering if there is anything official out there. I was talking to one of our guys that had an engine failure in the van just a couple days ago.

I know from over my way that P&W came to one of our bases and did some scoping. After a couple went down in the last 12 months and some compressor stalls in cruise something is going on. From what I've heard numerous defects have been found, new power sections have been given out and "further testing is on-going".

That's kinda scarry. The PT-6 in most applicatinos is rock solid. Hopefully it was just a bad spell of QC at the factory

Does this have anything to do with the drop zone C208 that "dead sticked" about 2 weeks back in Indiana?

You could check for SB's from Pratt & Whitney or Cessna. May be too early for an official AD yet. I'll bet P&W knows something! It could also be a lousy rebuilder. It's certainly happened before with piston engines.

I saw a hot section from a Caravan a week ago that had just been replaced, it had cracks in several of the blades. It was on a trend monitoring system. I'm not sure how effective this system is but, I'm thinking some failures could be caused by operator mishandling the rather than manufacturing defects.

Just thinking out loud but how do you mishandle a PT-6: Maybe running with low oil(shouldn't have anything to do with the blades) hot starts(a little extreme) Putting a lot of hrs on one(Thats what it was made to do, run) Over Torque(someone needs to be paying more attention to the gauges) The PT-6 is a great engine that can withstand a lot. It's not bulletproof but it is as good as they come for single engine flying, as long as the manuf. is producing them correctly.
