Wings, Wing Tip (Part 8)

Today was a very LONG and productive day!  In previous work session(s), we completed the left Wing Tip Fairing up to the point of trimming the trailing edge of the Faring to match the trailing edge of the Aileron AND installing the “new” landing light insert (more on that in a later work session) for the AeroLED lights.  I started today by trimming the Fairing “flange” to the required 1/2” [12.7 mm]....I didn’t take any pictures after completing the trimming, but man look how fast I’m going.....

After the trimming was completed, the next step was to match-drill #40 the Wing Tip to the Wing (using the pre-punched holes).  The first picture below shows the completion of the match-drilling on the Top of the Wing.....

.....and on the bottom of the Wing.

Next, the Wing Tip was removed, the holes used as #40 drill guides were final-drilled #27, deburred and dimpled for a #6 screw.  Here’s the forward part of the Wing showing the dimples on the Top and Bottom Skins.....

.....and the aft portion showing the dimples on the Top and Bottom Skins.

That essentially completes the preparation on the Wing itself.  Now, we’ll shift work back to the Wing Tip.  Just like with the left Tip, the right Tip also gets 42 K1000-06 nutplates installed on the Wing Tip flange.  To do this, use the center screw hole on the Flange and a K1000-06 nutplate to locate the nutplate attach holes.  The nutplate attach holes get match-drilled to #40 and countersunk to accept the head of an AN3426AD3 rivet.  The center screw hole also gets countersunk to accept the dimpled Skin from the previous step.  The following pictures show the completed process.....

All of the 42 nutplates have been installed using AN426AD3-4 rivets and the Wing Tip was temporarily screwed into place on the Wing.  Here is the right Wing tip with all the nutplates installed.

There is still a little bit of trimming required to complete the final fit.  I found it much easier to see what trimming was required with Tip actually installed on the Wing. This shows the clearance between the Tip and the Aileron in the down position.....

.....and in the neutral position.

I’ll complete the trimming during the next session.
