Trim Servo Installation Mistake
My friend with only about a couple dozen hours on his 12 had a harrowing day. He encountered violent vibration and control problems, slowed down to 80 and regained control, and landed without bending anything.
Postflight exam revealed the trim servo had busted its threaded rod from the servo, PROBABLY secondary to the nut coming off of the pivot bolt, and the pivot bolt moving out 3/4 of an inch or so. It is my guess that the cotter pin was never placed properly in the pivot bolt.
