Theoretically at least, you would think that CTM would cause the t/r to 'fine out' or go to a neutral pitch setting and on some aircraft this may be the case. My experience of later model 205's and the 212 in this situation is that if t/r control is lost, the blades will go to maximum pitch (or the full left pedal position on the 205/212).
In this case, where control is lost on one blade, the loss of t/r track (with one blade at max pitch and the other where-ever the pilot puts it) would result in significant levels of vibration and in a very short space of time, the loss of the t/r assy or possibly the t/r g/box. Not good either way.
The only way for the pilot to reduce the vibration would be to apply full left pedal and an armful of collective to fly away. He'd have to be a very brave chap to do this and the initial reaction I think would have been to close the throttle and dump it as described by T&B. If he did go down the flyaway route he could then attempt a run-on landing by gradually rolling off the throttle. Bristow in Duri, Indonesia used to practice this after a series of t/r control chain lock-ups on the 205's before they were modified to push/pull rods.
