Removed the ailerons and checked against the drawings to ensure all the rivets, screws, etc. were in place. Re-installed and inserted the 7 screws to hold the aileron in place on the wing and verified the gaps between the aileron and wing are within spec. Fabricated and installed an interface rod between the aileron and control mechanisms. Adjusted the assembly so that the control mechanisms are in the correct locations for the aileron neutral position and the aileron up position stops at 20deg.
