Shown below is the final assembly of the Aft Gear Brace Assembly. There are four parts that make up the Assembly:
1. F-01448A Gear Brace Angle
2. F-01448B Gear Brace Bar
3. F-01448C Gear Brace Brackets
4. F-01415A Seat Rib Angles
The Assembly was first clecoed together to allow several holes to be #30 final-drilled, 1/8 final-drilled, dimpled #30, and countersunk. Once all that was completed, the Assembly was riveted together using a mixture of AN470AD4-7 and AN426AD4-7 rivets. Here is the forward side of the Assembly showing the manufactured heads.....
.....and the aft side showing the shop head side of the rivets. The rivets were very easily set using my pneumatic squeezer and produced perfect results.
The Aft Gear Brace Assembly will be attached/riveted to the Center Bottom Skin as shown in the picture below. (The holes in the white circle will not be riveted at this time). I’ve inserted all the AN426AD4-4 into the appropriate holes and taped them in place. Here is a close up of what it looks like.
And here is an overview with both sides.
The Aft Gear Brace Assembly was put into place on the rivets shown above. I backriveted the Assembly to the Skin and the rivets turned out perfect. Here is the completed forward right side.....
