My previous comments about the number of single engine turbine failures wasn't trying to open up the single vs twin argument and I've crossed water in a PC-12 as a spare autopilot in the RHS and did a lot of time in the LHS of a PC-6 so happy to fly in them.
I can't find the statistics at the moment but when you read the factory advertising the pitch is you are more likely to win the lottery than have an engine failure , seems like a lot of potential lottery winners out there.
As a previous poster said it could also be that some of these engines are on their 3rd or 4th overhaul which could be starting to affect the statistics.
