Way i was always taught to deal with it in the hover was to close the throtle(s) and cussion the touch down, reason being (if my knowledge of PofF is correct

) the tail rotor provides counter torque power-on and friction power-off, by closing the throttle(s) you take away the drive to the main and tail rotor and so the a/c wants to yaw the other way, in a normal auto the tail rotor provides friction to stop this happening. So by closing the throttle with a stuck pedal (or total loss of the tail rotor) the yaw rate slows, maybe even stops, and you can use the remaining Nr to cussion your arrival at the ground. I have practised BOTH left and right pedal stuck and also total loss of tail rotor, all in the hover and this works.
