During the last work session, I riveted the Aft Gear Brace Assembly to the Center Bottom Skin. Today, I will rivet the F-01416B-L & -R Seat Rib Angles. Below is the right side of the Assembly showing the manufactured heads of the single AN470AD4-7 rivet (on the top) and the two AN470AD4-8 rivets on the bottom.
Here is the aft right side showing the shop heads.....

Prior to riveting the Angles to the Aft Gear Braced Assembly, the plans advised to make sure the F-01416B Seat Rib Angles and the F-01415A Seat Rib Angles are parallel with one another. To do this, I used a ruler to verify the same measurements at the top and bottom of the Angles. The lower measurement is 9 7/8” as shown below.....
.....and 9 7/8” at the top. Once those measurements were made, the Angles were clamped to the Assembly, one of the rivets was partially set, re-checked the measurement, and then completely set the rivet. I completed the same process for the remaining two rivets.
After this was completed, the F-01404 Bulkhead was clecoed to the F-01484 Center Bottom Skin as shown in the plans excerpt below.
This is what it looks like.....
