Horizontal Stabilizer Outboard Rib and Aft Elevator Push-Pull Tubes

We decided to install the aluminum elevator outboard ribs in place of the foam option.  After deburring the CNC cut parts we aligned the ribs, drilled holes in the leading and trailing edges of the horizontal stabilizer, and finished the process by installing the rivets.  We also assembled the elevator push-pull tubes using 0.625″ aluminum tube and machined threaded inserts.  The inserts were located in the tube and then drilled and fitted with 4 stainless rivets per end.  You can see the push-pull tubes in action in a previous blog.
