Brief Description: Fitting the Vertical Stabilizer--Rear Spar Align
The final alignment of the vertical stabilizer requires the rear VS Spar assembly be located exactly 7 11/32" from the top of the F-718 longeron to the top surface of the VS-410PP rudder hinge bracket. In the first picture I am measuring the 7 11/32" and making a mark above the rudder hinge bracket. The third picture shows the rear bulkhead assembly and longeron aligned on this 7 11/32" mark. Next I will temporarily clamp the assembly and take measurements from the tip of the vertical stablilizer to both tips of the horizontal stabilizer. I'll adjust the vertical stabilizer until the measurements are equal and the stabilizer is truely vertical.
