Started this morning by match drilling the left Flap. The three Flap brackets also had to be match drilled. I had laid out and predrilled each bracket mate, so it was very easy. All was disassembled. The spar, trailing ribs, nose ribs and skins were given a final deburr and then scotchbrited. Finially, all parts were dimpled where needed. I then started to assemble the right Flap. I got it all assembled and match drilled.
