Brief Description: Installed Main Ribs and Rear Spar Assembly
Riveted the 2 Rib Doublers to the corresponding Main Ribs. Completed all the steps in page 15-04 consisting of riveting the 13 Main Ribs to the Left Spar Assembly. Match-drilled #30 two holes in the aft flange of the most inboard Main Rib. Riveted the Left Rear Spar Assembly to the aft flanges of the Main Ribs. It was raining most of the day today and could not do a lot of priming. However, I was till able to prime 5 W-1208-R Nose Ribs. I used Mar-Hyde primer this time since it seems to dry faster and sprays evenly even when the temperature is cool.
