Worked on Feb 5,6,7 on horizontal stab. Few weeks earlier I install front and rear spar for the H-stab. At that moment I had a lot of measurement to do in order to get the stab alligned correctly. Now that I put back those spars, the measure are off by a few millimeters. Mike at BushCaddy give me an easy way to align correctly the H-stab by simply using a digital level and put it near the fuselage then at the tip and we must get 3.0 degree. That's it. I spent a few hours to get the stab structure to that 3.0 degree, then positionned, marked and drilled the top and bottom skin.
