Brief Description:	Drilling the Horizontal Stabilizer (RH)
Marked with Sharpie centerline on HS-404 and HS-405 rib top and bottom flanges. Aligned marked centerline on flanges of HS-405 and HS-404 ribs to holes in HS-801PP skin. Drilled #30 and clecoed aft flange of HS-405 rib to HS-603 RSA, using holes on the latter as guide. Removed and cleaned pieces. Reinstalled HS-405 rib and aligned top and bottom flanges with centerline to HS-801PP skin holes. Match drilled #40 HS-405 rib attach holes using HS-801PP skin rivet holes as guide. Drilled #40 holes on the fwd side of fwd flange of HS-405 according to SEC D-D, DWG 3. Drilled #40 holes on the aft flange of HS-404 according to SEC D-D, DWG 3. Ensured holes were drilled with proper distances and clearances. Once everything was clecoed, and ensured all ribs where in place, started drilling and match-drilling all HS-801PP skin rivet holes to HS-702 FSA. Clecoed HS-810-1 and HS-814-1 reinforcement angles to HS-702 FSA. Drilled and match drilled #40 holes according to SEC D-D, DWG 3 the following: front flange of HS-405 rib to HS-702 FSA to HS-810-1 and HS-814-1 reinf. angles. Then drilled and match drilled fwd flange of HS-405 rib to HS-702 FSA to HS-404 nose rib. Ensured proper edge distance according to plans and drawings. Drilled/Final drilled and match-drilled to final size (#40) all rivet holes attaching the HS-801PP skin to rivets and spars. Marked finished holes with green Sharpie. Right Hand Horizontal Stabilizer assembly set aside for storage.
