Brief Description: Fitting Horizontal Stabilizer to Fuselage
Clamped HS in place on the aft fuselage with the prescribed shims and and spacer, and took measurements to conform zero degrees angle of attack. The aft tooling holes in the HS-00005 are not on the chord line, so they aren’t useable for this measurement. I used 3/16 steel rods through the forward tooling holes in the HS-00006 and HS-00005 ribs and obtained the following measurements:
Given the longitudinal distance between the sets of holes, the AOI of the HS calculates to about 0.35 degrees nose up. This seems a bit odd, so I will try to figure a different way of measuring.
