Yeah I had an engine cut out on the CAP-10 during a certain manoeuvre - I'm sure those that have been there can guess which one it was. Only happened to me on the one aircraft though. Apart from that, damaged the tailwheel on my final flight because I flared too soon and dropped her onto the runway pretty hard. A guy on another course at the time also had a problem where he accidentally knocked the fuel valve closed which shut the engine down.
I doubt those were the pressing issue though (surely this is tame in comparison to an operational type or the PC9?), plus it was a very enjoyable aircraft to fly!
