TBO article is a good read.

At the end of the day, the $45K I assume was the cost for rebuilding both engines on the subject aircraft.

I still try to understand why an aircraft engine rebuild cost is so expensive. If a component measures within tolerance, does it get replaced anyway? What is the cost of bearings, cylinders, pistons, valves, guides, etc., assuming the crank, cam, conrods are within spec and reused.

Compared to your standard Porsche 911 engine and replacing like components.

Splane to me Lucy.
