This story appeared in the Boston Globe yesterday, regarding an accident that occurred a few years ago. The information is pretty sound, there is a history of problems with these parts.
We install a secondary spring to all our C206 throttles, to ensure that in the event of a linkage failure it will to full throttle.
Thought it might be of interest to anyone unfamiliar with the history of this installation.
