01/09/19: 4Hrs 2. Material was trimmed from the cone's F-1282 skin. 3. F-1284 L&R were riveted to F-1283A&B. 4. F-1283A&B were clecoed to F-1282 L&R.
01/10/19: 3.25Hrs 5. F-1282 L&R were used to match-drill #30 holes into F-1283A&B. 6. F-1283A&B were riveted only to the J-stiffener of F-1282L&R, because of what we believe was a manufacturing process, the holes on the left-side stiffener did not allign with the ones on the skin, it was either alligning the bottom ones or the side ones. We were instructed by vans to align the ones on the bottom, and use a shim to fill the gap that was caused on the sides, the shim we used was 1/16" of thickness and because so, the rivet that we used changed from AN470AD4-4 to AN470AD4-6. 7-9 The bottom skins were placed on sawhorses and the frames hooked to the J-stiffeners and were clecoed onto the skins.
