RE: Turbine life expectancy
Based on the small quantity of turbine fliers I have contact worldwide (knowing more than one language and having web access is fun) in the last 10 years I can affirm than 7 persons is a significant fraction of deluded people...
And yes, even if the owner is completely honest he didn“t knows what is happening inside the guts of his engine.. and then the problem can pop out in your hands.
As the "sweeping generality" of comparing cars with planes it is pretty much common sense. If you buy a good new car (a BMW for example) , it is highly unlikely that any problem will arise or even if this happens, you have a full factory warranty. Not the same if you buy a used one.. you will have to put the luck variable in the equation. Same as buying a used Jetcat.
