Aileron Torque Tube Nuts

[ERushing]

Hi Guys,

I sent this one in to Vans first thing yesterday and still have no response. It's after 4PM West Coast time so User support is closed. Thought I'd just bring it to the braintrust.

On page 23-7 of the Wing plans, an AN364-428 nut is called out which, I believe, is the low profile self locking nut. I went through the inventory 4 times and didn't see any sign of this nut. I can always order a bunch of nuts from ACS but wanted to see if anyone else ran into this? My eyes are getting old and maybe I just missed it in the inventory!

Anyone run into this??

BTW - Wing bottom skin riveting should start on Monday or so! Very close to finishing up the QBwings! (Minus the tips, of course...)

It must be your eyes. My plans call for AN365-428, not 364 The 365 is standard profile nyloc nut

I can scan it if you want, Bill The CD plans and my paper plans definitely call for the 364. The 365 fits but has no threads above the nut when fully torqued... which is why I figured it needed the 364! (It's the nut at the end of the two threaded pushrod ends.

Thanks for the quick reply!

As with all things on a Van's build, use the right rivet/screw/bolt. The planes are a great start, but should not be viewed as infallible. For your specific issue, use the next size larger bolt and a standard 365 nut with a standard washer.

I'll call ACS and order 'em. Unfortunately, the bolt goes on a threaded insert that goes into the end of the torque tube collars.

Just was curious if anyone else has found this omission in the inventory or error in the plans. I suspect it's probably a recent change in the plan and the inventory just hasn't caught up yet.

I might also try a 960-416L washer to see if that gives me the required "at least 1 full thread" showing w/ the AN365 nut.

Have a great weekend!

I just looked at my paper plans dated 2010, and it called for a 365.... Threads need to show, maybe they changed it to 364 and forgot to change the PL to provide the part!

My plans are dated 1/28/13 and they also call out the 428

It was a change. All early -10s had this problem. I notified Vans and they added the change.

Eric, I think you and I got our wings about the same time. My plans also call for AN364-428 which were not included in my kit either. They must have updated the plans without updating the hardware bags. Your eyes are spot on.

Might call Vans on Monday and see if they'll ship 'em to me for free versus calling ACS and paying $15 to ship $0.50 worth of nuts
