Preparing the Center Fuselage – 5

It is important to note that the rivets at the intersection of the spanwise row across the forward F-704 bulkhead and the fore-and-aft lines along the stiffener are shown as AN426AD3-6. I machine countersank these holes through the F776 skin and into the bulkhead. Rivets through these holes would later attach the floor stiffeners and a smooth inside surface would help fit the stiffeners properly.

Once the bottom skin was clecoed on, I fit and drilled the F-704H side doublers to the center section.

Time: 4 hours.
