Rudder horn wear
I searched the archives but didn't see anything specific to rudder horn wear other than tail wheel spring holes. After nearly 1,000 hours I'm starting to notice the holes in the rudder horn that attach the rudder cables are starting to elongate. Opening up the hole and installing a bushing would be one fix but was wondering if others have seen the same issue and what your fix was.
Thanks,
Gary

AN42 Eye Bolt
AN42 Eye Bolt is one option.

Use eyebolts through the horn and tailwheel arm.

A bushing should certainly work Gary. I was surprised when we built our -3 that the plans actually CALLED for a bushing (at least on one old page....it wasn't present on another newer one - such are the plans in the RV-3). So if you have access to the right bushings, I'd think it should work fine.

Also experiencing some wear on my RV-4 :-/
Maybe bushings like these could work: http://www.aircraftspruce.com/catalo...clickkey=72672
Question is which size and what kind of tool to use to press fit them into the rudder horn.

I'd go with short eyebolts.

I noticed that on my kit too, but the bushings weren't included. Sigh.
I've got some 1/4 inch stainless tube that I might install for bushings when I'm ready to put the fiberglass tips on the rudder. That'll be the next time I get my hands on it.
