Problem identified

Hello,
Too many excuses but in my opinion it all came down to improper logging in aircraft logbook. When aircraft was bought, maintenance didn't or wasn't or missed (too many excuses, i lost track) to include past logs to new (our) aircraft log. Bottom line is our team finally got hold of p&w guys and have some specialist come over to inspect the engines. Turned out engine time is way past its limit. As per p&w "it's a miracle that the engine kept running as long as it did, now there's a disaster waiting to happen".
Conclusion, I'm very impressed with the pt6.
I'm very grateful that none of you guys experienced this,having me worried and was able to escalate the issue.
***@uplinker- sadly yes.

Chain of events:
*Aircraft bought,
*Logbook wasn't updated properly(I'm not too sure about this but this is the only reason i can come up with...having the engine go beyond its time limits like that)

*Aircraft ok
*Pilot experienced problem.
*Squawked the problem and logged it.
*Inspected none found.
*Became severe.
*now both engines are acting up
*Head mechanic for the shorts advised a/c be grounded but was overruled.
*Became more severe.
*Pilot denied flying plane.
*Aircraft grounded.
*Inspected properly by p&w
*Shaft and fins has visible wear and tear. Sorry i cant be more specific. they were all in a hurry to resolve this and simply stated that engines needs to be replaced (i was able to talk to some of the mechanics that there were cracks in the shaft and chipped off fins)
Resolution:
Engine for replacement

Well, as annoying as it is, that's that.

Thanks again guys, your replies really helped.
Chris
