I am a relatively new owner of a Synergy built RV-12 N233VA Serial Num 12007. The airframe has about 1350 hours on it. After accomplishing SB-00053 I was inspecting control cables in the tail. To me operating the rudder pedals created more scraping noise than I thought was normal.
Upon inspection I found that there was no plastic insert (SB750-10) in either the left or right side rudder cable supports F-1238L and F-1238R. I found no evidence that SB750-10 was ever installed. They were not hanging on the rudder cable anywhere and they were not laying on the bottom of the tail cone. Also, the plastic sleeve protecting the rudder cable in this area was worn all the way through so that the rudder cable was rubbing directly against the F1238 support. It is clear that the cable has been rubbing a long time.
It is hard to believe these just fell out and disappeared but I could be wrong. Has anyone else had any issues with these plastic guides for the rudder cable? If you didn't build your -12 it may be worth a one time inspection. It is pretty easy to see this area with the top tail cone cover off.
Of course I plan on installing SB750-10. The bigger problem is replacing the 10" plastic sleeve in this area. It is worn all the way through. The rudder cable itself looks to be in good shape. I am not the builder so I am unfamiliar with this assembly. Can the rudder cable be disassembled to allow replacing this sleeve near the tail or will it require a new set of factory built rudder cables?
