I flew with a boke that crashed one whilst instructing, and he was in a newly appointed position when I flew with him. found him to be quite a good instructor. sometimes one can make a mistake and learn from it. As we all know, it doesn't take much to prang one.......especially whilst training, and being a new instructor the margins would be smaller. I would imagine a possible employer would take that into account. but the engine overspeed as well.....Hmmm, maybe it wouldn't be looked apon as being an advantage to add it to the CV.
