My name is Justin and I worked under my prop today.....
Serious thought about this post as I was checking something on my fuel servo. Given the horizontal positioning and my removable scoop, I literally am bent under the prop... if it was to spin my head would be removed. Here’s my mental checklist
Mags - Off, keys removed
Fuel - Off
Mixture - Cut out
Prop - Adjusted while standing and rotate it as if it’s ready to spin
I do the exact same thing before putting a tow bar on to put the plane in the hangar and it’s served me well. This would have not benefited the OPs mentioned case. I wasn’t there but to me it sounded as if he tried to taxi, realized the wheel chalk was in place and send his wife out to fetch, not wanting to shut down. Why? I have no clue, maybe he didn’t like hot starts, maybe he didn’t like his wife, maybe they played weird games with loaded guns... whatever the case is, if you’re ever in a similar predicament then go ahead and shut down your engine. Greatly remove the risk of your passenger getting injured and going pirate.
