Brief Description: Final drill spar splice angles and left stab skin
Attached the spar splice angles (HS-810-1 and HS-814-1) to the horiz stab front spar (HS-702).
Ensured the front flange of HS-405, HS-702, HS-810-1, HS-814-1 and the aft flange of HS-404 were pulled up tight. Reclamped the upper and lower flanges of HS-404 to the stab skin (HS-801PP. Drilled the HS-405 to HS-702 to HS-810-1 and HS-814-1 to HS-404 inboard rib attach holes. Used the holes previously drilled to #40 in the forward flange of HS-405 as a guide (see SEC D-D DW3).
Match drilled all the remaining holes attaching the HS-801PP horiz stab skin. Drilling sequence started at the intersection of the HS-708 center rib and the rear spar and proceeded up along the rib and outward toward the tip.
Removed the skin and drilled the outboard most holes on HS-814-1 and HS-810-1 (spar splice angles). Removed HS-810-1 and HS-814-1 for further prep.
