Clearing out the damage!

We're almost done clearing out the damage.  We peeled back the wing skins to a point where we can access the spar.  Thanks to Les and Kyle Schweizer for emailing me the spar splice repair diagram!  Based on what we're seeing, the spar splice will be centered three ribs in.  That will guarantee a straight spar out to the tip.

Once the repair is done, we'll start the reskinning from the tip inward, trailing edge to leading edge.  We also looked at the right wing and it's no where near as bad.  I also found out from K and L Soaring that they can repair my damaged tip rib.  The one on the right wing isn't bad at all.  That's a big load off my mind!

Kele Fergestrom got to exercise his brand new A/P license today and helped immensley with the rivet removal.  With 3 A/P's helping me, I can't go wrong!  Mahalo to Jason, Justen, and Kele for the kokua.  Now I'm going to have to wait for the FAA to give me the go ahead on the spar splice.  Once that's in hand, we'll start ordering the parts and materials for the splice and re-skinning.

I've reserved a new N-number for her - N374AC.  It stands for Kevin's old unit - 3rd Battalion, 7th Regiment, 4th Brigade, Alpha Company.  I'm going to have the 3rd Infantry Division patch on her tail as well.  Planning on painting her cream overall, with green trim in a pattern similar to this 1-26:

Top skin removed.  Splice will probably
be centered on that third rib.


















Bent, damaged, and corroded spar.  All this will be
removed and replaced.

Wing tip disassembly

The left wing was the most severely damaged.  The spar was bent and the skin was damaged.  There was a lot of dissimilar metal corrosion due to the interaction between the aluminum and the steel mounting bracket for the wing tip pogo wheel.  Not too concerned about the corrosion since we'll be replacing all of the metal in that area.  I did find out that Jason is real good at drilling out rivets!

The plan is to fix the spar and ribs without taking off too much skin.  That way when we start to re-skin her, the underlying structure should be straight.  At least that's plan!

The internal structure doesn't look too bad.
That L-shaped aluminum and it's lower counterpart
 will be replaced.  Hopefully, the shear web is okay.
