Fuselage, FWD Lower Structure (Part 9)

Tonight’s session concentrated on attaching the F-01453-L & -R Muffler Shroud Sides to the F-01483-L & -R Forward Bottom Skins.  To start, the bottom side of the lower flanges of each Muffler Shroud Side was cleaned with solvent (I used isopropyl alcohol).  Then, a small 1/16th bead of fuel tank sealant (I used Flamemaster CS 3204) was applied to the bottom of the Shroud Sides where the flanges rivet to the Forward Bottom Skin.  Finally, it was clecoed and riveted.  The two Shroud Sides used 44 AN426AD3-3.5 rivets (22 on each Side).

Pictured below is the left Forward Bottom Skin with the left Shroud Side prosealed and riveted.

Here is a closer shot of the inside (or upper) portion of the Skin.....

.....and the opposite side (or lower) portion of the Skin.  You can see the rivet line at the top of the Skin.

Pictured below is the right Forward Bottom Skin with the right Shroud Side prosealed and riveted.

Once each Bottom Skin and Shroud Side were riveted together, I used MEK to clean up the excess proseal and make it “pretty”.
