on/off friction?  Best not do that.  IF you have a SAS actuator runaway in pitch or roll the rotor disc is going to move, hopefully not towards anyone walking under the disc, assuming such a runaway could lower the turning disc to head height.  In my career I had one such even after landing, that, in 22K hours.  Remote, but who wants to be in court over whacking someone with a rotor blade?

Land, disengage stability systems, friction cyclic or have PNH hold cyclical centered, disembark/embark, reverse sequence, etc.
