a few years ago a student at my flight school didn’t turn the ignition fully off on his plane and pushed it back into its parking spot after a flight. at first without issue, but unfortunately, the next morning when he came back to take it up, he started his pre flight routine while one of the mags was still hot and when he slightly pushed the propeller he turned it ON.
so as it goes, tragically, his head got swiped clean off… 🩸he was found by a nearby mechanic face down bleeding out that morning on the pavement.
so all to say, a very minor thing you forget to do in a dangerous job can easily become fatal and disastrous, so this is just a reminder/recommendation to double check every box when lives are potentially on the line.
