Perhaps I should clarify my use of the word "failure". The break-out mechanism may have done what it was supposed to do -- break.
My understanding is that there is no mechaninal "failure", the breakout mechanism comprizes cams, springs and rollers, to allow disengaging each yoke from the other.
It is rather a matter of pull/push overcoming a springed detent.
