While setting the travels and clearances are important, even with them set correctly (which mine are), a stiff gust WILL deflect the rudder far enough to cause damage. Happened to me when my rudder lock failed years ago. Current rudder lock is much more robust because of that event.

I'm building a Zenith and I'll have to double check but I don't think the ones included with the kit are aluminum. Is the builder you are referring to using the stock parts or aftermarket parts?

I am wondering if it is not possible that the nut was removed from this bolt by someone in the paint shop?

The reason I ask is that anyone familiar with the RV-9 knows that it is a huge pain to disconnect the push/pull rod from the aileron with the aileron mounted to the wing. When I have to remove an RV-9 aileron I disconnect the push/pull rod at the bellcrank and pull the rod out while removing the aileron.

Perhaps someone in the paint shop did the same?
I was wondering the same thing as Scott. This is one of the areas I always look over very carefully. Seems like the bolt surely would have fallen out if it was like this for any period of time. And most likely would have been spotted during an inspection or pre buy.
This is why I prefer to be alone while inspecting so as not to be distracted. Ie I start looking at an area while being bothered to help someone find a tool or hardware or the phone rings or anything that might take your attention away at a critical time from what you should be focused on.

I hope aluminum swage sleeves are not stock, but I also recognize an EAB kit vendor may supply whatever it sees fit, regardless of accepted practice.

Default Nut

It seems the unknown here is who either missed it or took it off. And if you are unable to verify which I would go over it myself and also have a very qualified person do another inspection before it flies again. Cheep insurance I would say even if it cost half of what you paid for the first one. You only get one go around not second times in life.

Evidently it just wasn?t your day. I?ve flown a 30% rc Yak after the right aileron control horn popped off in flight. The controls were mushy but it was still quite responsive. There?s a J-3 cub air show pilot that intentionally jettisons one aileron in flight. You can find him on YouTube.

The minimum number of planes one should own is one. The correct number is n+1, where n is the number of planes currently owned. This equation may also be re-written as s-1, where s is the number of planes owned that would result in separation from your partner.

Can you tell whether or not it's aluminum by looking? If so, how so?

thanks!

Try a magnet to check.

Best regards,
