Yeah! All done with step #41. There was an error in the build manual that caused me some frustration and back stepping. The note on page 99 (12/29/04, rev a), Step #41, Note #5. Should be simply stated as: Nose Rib 6 & Nose Rib 12 should have #30 diameter holes on both the upper and lower leading edge skins. These are the skin splices at BL 69.0 and BL 130.75. To improve the build manual, Step #36, last paragraph (page #86) should be corrected to state the same thing as noted above for note#5, step #41. The current language is incorrect as it referencing the wrong BL location. This has caused me to backtrack to resolve the issue. Fortunately, making holes bigger is easy so the problem was solved and just cost time.
