Diesel aircraft engines and are the light jets pushing out the twins?

Well, one problem is that the assertion that turbines are more reliable is,
in my opinion, unproved. A well-maintained piston engine can be VERY
reliable, while a poorly maintained turbine might not last very long at all.
It's hard to know for sure, because most turbines are operated in an
environment where there are strict maintenance standards. Those standards
applied to piston engines might well result equally reliable piston engines.

Perhaps a study of the durability of engines used for things like APUs, rather than
aircraft powerplants would be informative. Such engines, both piston and turbine, are
likely to be only moderately well maintained.
