You mean the Sully deal? Piston engines don't eat birds like jets do. Nor do they have high thermal stressed (there is no cooling cycle in a turbine, it is constant flame) high centrifugal force stressed parts running into the 10,000 plus rpm range, nor do they cost into the 3 or more millions to rebuild.
Piston engines are more complex and have a significantly higher moving parts count and those parts, rather than spinning around a single plane, have constantly shifting forces. On top of that, the turbo slapped to it will be spinning at a much higher speed than a traditional turbine. There is nothing inherently more stressed about a turbine, that's why they run for decades in power plants and why, even choking on exhaust, turbochargers last as long as they do.
You seem to have some vendetta against anything using a turbine (C-130 for example) and it strikes me as pretty weird at this point, as you've had multiple experts completely contradict whatever agenda it is you are peddling
Our company owns a couple of planes, one is a Cirrus SR22 Platinum, which replaced an SR20. This is used for short trips typically. The turbo has been replaced as well as a few other items on it. The 2nd is a Citation Mustang, which is a small 7-seater Jet, used for longer flights. The operating and service cost differences between the two aircraft are not massive, and an overhaul on the two turbines once they reach their hour limit isn't insanely expensive.
The TBO on the Cirrus is 2,000 hours, vs 3,500 hours on the turbines in the Mustang.
The overhaul cost on the PW615F-A is ~$200,000; $57 per hour of operation.
The overhaul cost on the Continental IO-550-N is ~$60,000; $30 per hour of operation.
The plane we had before the Mustang was a Piper Navajo. It flew lower, slower, and was significantly louder. It had a 1,600hr TBO period at a cost of ~$40,000; $25 per hour of operation and you were putting on more hours, because it was significantly slower.
As you can see, these costs are not insane. The little Mustang will accrue fewer hours per flight because it is that much faster. Ergo, the number of trips we get out of the Mustang between overhauls is significantly higher, offsetting the higher overhaul costs.
