Completed the following task on the left elevator: * Back rivet the stiffeners to the E-701-L/R skins (See “Back Riveting”, Section 5.6). * Back rivet E-615PP to E-701-L. * Bend the trailing edge of the elevator (See “Folded Trailing Edges”, Section 5.7). * Rivet WD-605-1-L to E-702 and E-705. * Rivet E-713 to E-701, two rivets on the top and two rivets on the bottom (assembling this way eliminates the need for blind rivets). * Loosely place E-714 in place nested inside E-713 with screws partially inserted. * Insert the elevator skeleton into E-701-L/E-713 beginning at the front end of E-703/E-704 and then rotating the root end aft into proper position. * Rivet E-606PP to E-701-L along the bottom flange only. Leave the top flange unriveted at this point for installation of the trim tab hinge. Rivet E-606PP to E-705.
* Add sealant to the trailing edge ends of the stiffeners just prior to assembly. * Started riveting the skin to the structure.
