Aft Fuselage Assembly – 3

Now I proceeded to drill all of the remaining holes (except the ones for the F-706 bulkhead and the F-718 longerons) to final size.

I checked with  DWG 27A for the position of the F-792 rudder stop. I had to leave one hole open to match with the drilled hole in the rudder stop. I marked this hole so that it would not be riveted or dimpled.

When drilling was complete, I removed the skins. I then deburred the structure and the skins, dimpled as required, and clecoed the rear fuselage back together.

Time: 4 hours.
