Well, I'm back from my business trip but my green primer has not arrived yet, rib #9 will have to wait a bit longer. I decided to move on to the upper aft skin installation, first job is to peel the protective plastic of, I really hate that job, took me almost an hour to get the plastic off both sides. Before I install the skin, I drilled the wing walk part of the root rib doubler in place which can only be done from the inside whilst I have the skin on the table. I will use the same procedure as with the doubler on the right side for this one, i.e. when the fwd skin has been drilled in place take it off and use the overlapping matching hole to continue drilling the doubler from the inside.
