Interesting point about pulling form the prop.
There is an article in this months Pilot telling us that you should NEVER pull the aircraft by its prop (I think the reference may have been to props with csus but I cant remember).
This is totally contrary to my experience and all the engineers I have known quite happily "man handle" the aircraft by its prop - albiet I am always keen to ask people to hold the prop as near the hub as possible to avoid placing any undue stress on the prop (which perhaps is also ill founded).
