Today, I completed the clearance issue between the right wing aileron torque tube and the spar cut through. I used a new file to clean out the bottom of the pass through and am comfortable with the current clearance. Next, I worked on the flap linkage. I had one bolt that wasn't fastened where the flap torque tube left the mixing unit overhead. To do this, I had to unhook the mixing unit, the flap torque tube and the aileron torque tubes -- ugh! But got it accomplished. I then worked on the fuel system. I installed the new caps and the fuel placard decals near each cap. I also took some measurements on the sight guages to make some small brackets. Finally, I tightened the baffles on the lower part of the engine with safety wire.
