Real-life TBO

[kevin]

In my opinion, engines at TBO are valueless in aircraft purchase price. The owner is doing well to have gotten that far. I would not major the engines until they tell me they need it, but past TBO you can figure that you are going to find low cylinders, metal in filter, etc sooner or later, more likely sooner. Any major work required will trigger OH, even one cylinder down. So an owner who has been careful with the engines gets bonus value beyond TBO, but I would not pay for it in purchase price.

My opinion only.
