Fellow RV fliers: I started my conditional inspection today and while going over the airplane, my DAR hangar mate questioned me on the upper elevator travel limit on my RV-4 (I did not build this airplane, but I have been flying it for a couple of years). I hadn't seen it before, but the after limit of travel for up elevator is when the elevator horn hits a portion of the aft structure.
The measured up and down angular movement of the elevator appears to be correct but there is no up stop, or at least there is not one before the elevator horn hits the back edge of the opening it sits in. The edge it hits has made a chafing mark (groove) across the back of the elevator horn. I can't find anything on this in the build book I got with the airplane.
Can someone who is building or has built, an RV-4, and who remembers this part of the build help me out here? Am I missing a stop, is the groove immaterial, or should I put some sort of chafing protection in place? Any assistance would be appreciated. This looks to be a safety of flight item to me, but perhaps is in fact "as designed". Thanks!
Regards,
Lee...
