I would call that Pilot Error.
1) stop engine
2) if only one door, ask passenger to get out, so pilot can remove wheel chock and properly stow someplace safe.
3) all get back in plane, close door and restart engine.
Time for all of the above...approx. 5 min. max.

I agree 100% with your procedure here.

I’d say maybe 90 seconds tops though for shutting down, pulling a chock(s), and restarting something like a Cessna/Piper in the sub 200hp range.

Not sure if I’d call this one pilot error or not. But he certainly should have reminded the guy upon exiting the aircraft to be aware of the propeller. Usually that’s all the seed that needs to be planted to make the individual walking around the aircraft very aware of it at all times.

Our kids where born and thus far raised around aircraft of all sorts. There is hardly a day that goes by that they are not in or around them. It’s just the way life is here. They (9 and ~12) are very familiar with various types of aircraft and actually quite capable and confident in taking control of some types even at their young age.

Even so – I can assure you that if and when they are ever in a propeller driven aircraft, and either of them for whatever reason needs to get out. The engine(s) is shut down until they are back inside and seated. And never, are they permitted to exit a spooled helicopter without walking directly to and from the nose. (My parents 520N being the only exception.)

Luckly I rearly have to climb up something like that, the framers know what they are doing, and set the stairs, so by the time I need to get up their the stairs are in.

I would love to get one of my friends totaly smashed and have them pass out on that thing. I'd camp out for the morning scream.:D
