No Push
Really folks, it is pretty simple. If the surface, whether it be a flight control or a fairing etc, has an advisory such as NO PUSH - DONT PUSH - NO STEP etc it means what it says. Don't push on it, sit on it or step on it. There is a subtle difference in lifting an elevator up and down, moving a rudder left or right, moving an aileron up or down compared to exerting excessive force on them. A bit of good old fashioned common sense should be enough to tell what to do, or not do.
