# I will let you work out the rest for what happens if the bearing fails and what could possibly happen to the nut.
Apparently so - it will be interesting to see how the design complies with CS-29.
I am surprised that the attachment of the lever mechanism to the control shaft relies purely on clamp up with the nut. No key or index?
Maybe there should be a weak point in the shaft so that the integrity of the feedback is maintained so the servo does not go to full travel?
I am amazed that things like this can still develop in this day and age. Somehow folk have lost sight of the details.
