Placards: "No Push"
A number of surfaces, mostly control surfaces but sometimes struts, are placarded with the words 'NO PUSH'
Does this mean:
A - do not use this surface as a 'push' point of contact when manoeuvring the aircraft on the ground by people power. Say, pushing the aircraft into a hangar.
B - do not manipulate the surface, during the course of a pre-flight etc, for purposes of checking function.
I've always taken it to be the former option (A), but see a growing number of people interpreting it as 'B'. Since the average POH doesn't seem to specify, which is correct?
Please offer references as able, rather than just state hand-me-down information gained from Instructors / other Pilots
Thanks
