Yeah, I hear ya. I just don't think an occasional simulated engine-out

And I still want to know *how* it harms the engine. Exactly what parts

be damaged, and why?

Can we agree that idle power/full power engine management will cause
more wear and tear (AKA: "Damage") to an engine than steady-state
operation?

No, Jay, not until I know what the "wear and tear" is, and why increasing and
decreasing the power at short intervals causes it.

It's a serious question. Off-hand, I can't think why t&g engine operation
would be more harmful per hour than takeoff/cruise/land, as long as no
operating limits are exceeded.
