FIRST FOR MIKE:
Mike, I just posted two pictures to Maddog (Safety For Outboard End of
Aileron Torque Tube) the first was by mistake and is a large file. When you
get a minute you can delete it and keep the sized file with the .jpg
designation. Thanks.
Randy and I were not comfortable without a safety on the bolt at the
outboard end of the aileron torque tube. I emailed MAM and asked about a
safety for the bolt and the need for a CC-54 (tube ring) on the inboard end
of the torque tube.
Robin's response:
Because of the CC-54 already installed on the end of our tube, a bar with aThe CC-54 is not needed on either end of the torque tube.
It should be removed from the manual.
The AN4-13A bolt in the end of the torque tube is held tight by the
anchor nut and possibly lock tite.
It should probably have a drilled head and safety wired to a
.125 thick X 1/2" or 3/4" wide aluminum bar riveted longitudinally to
the torque tube and protruding past the end of the torque tube.
jog in it would be required etc. While thinking of how to fabricate such a
bar the idea of using an Adel Clamp came to mind. And that is what I used. I
just happen to have some #31's (31/16) on hand, a perfect tight fit for the
two inch torque tube. A small tab bolted on with the Adel Clamp and I was in
business. Oh, and a little one handed dexterity and a few #^%$*%^)^&_
working through the inspection hole. We used a AN4H-14A end bolt. The
picture posted to maddog shows all.
We also added a delrin washer/spacer we fabricated to take up the end play
created by the AIL-26 bushing and an installation per the manual. It slides
over the bushing. An added benefit of having the spacer is that a normal
bolt head will clear the support bracket. As you will see in the picture we
also used a castle nut and cotter pin on the rod end bolt. I know a nylock
nut is fine. We just like that irrational "feel good" thing when it comes to
critical nuts.
