Assembling The Right Aileron

Today, my goal was to get the right aileron assembled.  We did the table rivet hammer and bucking bar on the top skins.  We only had to drill out 4 rivets today.  Them rivets near the stiffeners are real bears.  A different bucking bar may have helped, but that space is tight.  Anyway, after getting done with the top skins, I moved on to the bottom skins and started pulling the CS4-4 rivets.

I went to pull the rivet in the picture below and it didn't "feel" quit right during the pull.  Sure enough, when the rivet shaft busted, I had a protruding shaft from the rivet.  Crap....  Now what?  I was able to push the shaft down and then I just drilled it out.  I was expecting it to take an hour to get this drilled out.  I got lucky.  I just pulled a new CS4-4 rivet with no further problems.

After I got everything riveted, I mounted the aileron brackets.  Pretty straight forward here.  I reference my trusty aircraft handbook to look up the torque values for these AN3 10-32 bolts and it gave a torque value of 20-25 in-Ibs.  I torqued them to the high end at 25 in-Ibs.

Don't forget your washers on the back side and I also had two threads past the end of the locknut.  I like to see at least two threads past the end of the nut.

The inboard bracket has three bolts and note that the center bolt has a washer on this side.  That is because in order to install this bolt, you have to turn it from this side since it secures to a nutplate.  The plans called for a 10L washer.  I tried to locate what the "L" means, but I couldn't find it.  I think that it is the thin washers.  Anyway, that is what I put in there.

Again, washers on the back side, two threads past the end of the nut, and torqued all hardware to 25 in-Ibs.

Both ailerons are done and the trailing edge looks as straight as can be....  YAHOO!!!  Now, back to the left fuel tank.  Tami can't wait to work with tank sealant once again.
