SAIB: CE-12-41 Flight Controls – Loose Glide Screw
Taken from the bulletin:
The FAA received a report through the Safety Difficulty Reporting (SDR) system of a jammed elevator control system on a Cessna Model 182S airplane. The jam occurred in flight in the neutral elevator position, and the pilot was able to land the airplane safely using elevator pitch trim control. A mechanic removed the control wheel assembly and discovered the screw (part number (P/N) NAS220-14), which secures the plug (P/N 0760681-1) and glide (P/N 0760651-2), had completely backed out and jammed the elevator control. A screw that completely backs out could jam the elevator in any position encountered during normal operation. There have been seven other reports of this screw being found with no or low torque.

I have done one of our 337's and can say it can be a pain in the butt. It's much easier to do if you remove the control wheel tube. On our s/n's we only have to do the right side

Part number NAS220-14 is the screw. Reference #24 on the figure attached. The plug mentioned in SAIB is part number 0760681-1(2) is the plug on #24.
Kim, I can only imagine that this is really a pain to access.

Has anyone found a loose screw in their yokes, yet?

Looks like the B models are not affected, according to this document.
