Located F636 shoulder harness anchors on longerons as shown in plans. Drilled all holes and deburred. Finished 728A drilling and riveting to F706 bulkhead. Although I had previously fabricated the F635 bellcrank, I removed the two rivets holding the spacer at the top and replaced it with a larger (in area) spacer to create a more solid mounting for the autopilot rod end. Made the two F786A top stringrs and drew a center line on them after deburring. Placed J stringers onto bulkheads. Clecoed on F775 rear top skin. Attached all 4 F656 gusset plates onto longerons and bulkheads and drilled holes. Trimmed and deburred F788 gusset. Clecoed in F787 stiffener rib. Clecoed on F774 forward top skin along with F788 gusset. Drilled all holes. Fitted F709 bulkhead after fluting. Clecoed on F709 and drilled holes. Removed clecoes holding top skins on the right side and fabricated F709B angle clip. Clamped clip on and drilled holes. Removed all skins, stringers, F787 rib and F788 gusset. Deburred F787 and F709B and riveted together.
