Today’s session was relatively short, but it accomplished a lot. We were able to install the 17 rivets shown in the black box below. These rivets took a little longer than normal because proseal had to be applied between the Muffler Shroud Ramp and the Center Bottom Skin (area shown in the white box). Applying the proseal was not all that difficult, it just took a little time. First, I removed as many clecos in the area around the while box holding the Center and Forward Bottom Skins together. This allowed me to create a space for the proseal application nozzle to get between the two pieces. Once the proseal was applied, I re-installed all the clecos and started shooting rivets. We worked from inside out as the plans directed. After installing all the rivets in the black box, we used rags and MEK to remove the excess proseal.
