Well, granted, the engines on your plane require a much more specialized
maintenance crew than the one Lycoming on mine. But in spite of the very
real possibility of human error during maintenance, as far as I know more
engine failures are prevented by maintenance than are caused by it. I would
be very surprised if you could find statistics to the contrary.

I'm a Lycoming-running statistic (n=1). I "lost" an engine because the
throttle cable came off months after the engine was replaced at annual.
Fortunately I noticed it on the runup. But it happened the night before
when I was dodging lightning on the approach to Durango. (I didn't notice
it then because I rolled in just ahead of the hail and was more interested
in getting under cover than parking perfectly.)

I have way too many examples of mechanics screwing up my plane.
