The only radial I have spent any real time behind was the Huosai (Nanchang CJ6 engine). The Chinese may have an appalling Human Rights record, but they build a nice, reliable, strong engine. Not a single hiccup in the nearly 7 years I flew it. Top quality maintenance had a lot to do with that too.
That engine failure in the 146 was a no warning, catastrophic type. Fairly woke us up at the time. And it was interesting to reflect on how we handled it. Not just from the point of sticking to SOPs, but how we handled it personally. I was operating the radio, and I can tell you, at one point my vocal chords contracted so I sounded even squeakier than normal, making it quite hard to talk. Just a physical reaction, nothing that I could predict or, possibly, prevent. I didn't feel panicky inside, but I guess some part of me must have gone into "fight or flight" mode. Only lasted a split second, but could have been a problem if it hadn't passed.
We were both very concerned during the flight to our diversion. As there was no warning or hint of anything being wrong, there was always the very slim possibility that whatever had caused one engine to go from full power to nought with a very loud bang, all needles in the red arc, then to zero, could affect the other 3 engines. Not a comfortable feeling at all.
Of course, with hindsight, once we knew what had caused the failure, the likelihood of that happening was very small.
Going back to the physical reaction, thats something you really cannot predict. Therefore, having all the SOPs/PFLs procedures so they are second nature will help when things do go to the dogs. Second nature should take over, while the physical reaction is doing its own thing in the background.
