While I agree the PT-6 is a very robust engine and as long as the maintenance history and hot-section checks out OK, you "should" be fine to operate the engine for many more hours to come.

Now that said. .I've got nearly 2000 hours behind PT6's ranging from 20's to 42's and every actual engine failure i have had, has been a PT-6 shedding the power turbine disk. One of these was in a KA-200 immediately after rotation, and the 2nd was a PT6A-20 during climb out.

So while the engines are built like tanks, and nearly indestructible, they do fail.
