No, gas turbines are much more reliable, and cheaper to service than reciprocating engines.

- jeffreyrogers 5y agoIt costs >$100k (potentially much more) per overhaul of a turbine engine. That's a lot more than it costs to overhaul a reciprocating engine (probably 10x more). I agree that they are more reliable though (part of why most helicopters use them, since loss of the engine is much more serious problem than in planes)
- baybal2 5y ago> It costs >$100k (potentially much more) per overhaul of a turbine engine Aircraft certified piston engines will reach that cost in overhauls much quicker than a turbine
- jeffreyrogers 5y agoThat is just not true. You can google the cost of overhauling a Cessna engine, it's nowhere near 100k.
- baybal2 5y agoBut you need to overhaul it way more frequently, and buy replacement parts, and consumables regularly.
