I did hear from other guys with that engine that the first few times it happened there was some push-back from the manufacturer that it was a user problem, not an engine problem. However, after the engines started coming back with the same issue, the manufacturer realized that it *was* an engine problem and they came out with a new compressor and started replacing the ones on the failed engines for no cost.

Different manufacturer, same issue and initial response. See Len's post above - it can happen to any of them...

If you want bullet-proof tanks, go with AMT's or old JetCat P-120's...

Good I just read the post, because I have been very worried, I am also a holder of one of the first K70G2 and today I will have done with it from 15 to 18 flights and at the moment without surprises but I am afraid it happens to me and I can not land the whole airplane in one piece. I just sent an email to the manufacturer, because I think I understand Barry, apparently it does not happen in all of them but who guarantees to me that mine will not fail!

Equally the wisest thing I think it would be to stop flying and send it for its update, to see that they answer me, I need more light about it!

Greetings.

2 posts back to back........Do you not think it more polite and gentlemanly to make your request privately and man to man? He does have a phone and an email.
Posting this in a public forum puts everyone involved (OK, maybe not you) in an uncomfortable position don’t you think?

My less than 2 cents opinion would be NO. This is something that needs to be discussed with the manufacturer/ manufacturer's rep in a one-to one fashion. In a perfectly civil world - no problem! But I really don't want/care/need to know whether your (pick an age) engine is refundable or not.
Good luck with whatever you and Barry decide.

No worries Greg, but yes you can return the engine DM, we would have to inspect before issuing you a refund.

Thank you,
Barry

I personally wouldn't stop flying, but knowing there may be a potential problem, probably keep it higher in the cone, so if there's a problem I could still try to glide it in. But if you are concerned, please feel free to send it in, but we just don't have an upgrade at this point, so it will at least be in the queue.

Thanks,
Barry

To be fair to the investigation process of metal failures, yield strength testing / investigations are very complex. There are many parameters that are considered when coming up with a final report of what went wrong. I hope that when Barry says they are looking into this that they are using a metallurgical lab that identifies material defects and structure failures.

The information coming out of that lab is only as good as the factual information we help provide to Barry on the conditions at the time of failure. The who's, what's, when's and where's are important. A turbine failure for a winter flyer at high altitude and ambient temps in the 20's may not be the same for me who fly's at sea level with an ambient temp of 102F. I remember a time that used turbines being flown in a certain area were being sold here and causing allot of issues. When looking into all this, the people selling them weren't telling folks that they were being flow in a sandy area and the engines were basically getting sand blasted internally.

Again, just trying to be fair to both sides. Failures happen.

The problem is that our flight path only has 160 meters and, on the outside, a lot of rocks and ravines, in short, it is not especially suitable for turbine stops.
And Barry knows if the problem is in all the production of the k70 or all its customers? It seems that there is a customer who has already made 140 flights to his!
