diethelm,
That's why they design the parts to be strong enough. New machines are subject to a proof & ops test, they jam the head and stall the servos. Since the big SA makes dual stage hydraulic machines, one stage has to fly the aircraft through the whole envelope, but the parts have strength to take full tilt boogie with both stages operating. Not only statically, but all those parts are good for fatigue as well.
