center section. Adjust the flying wires to center the center section over the fuselage. This is indicated by
having equal distance between the plumb lines and the top longerons. Adjust the flying wire tension by
turning both wires equal amounts until 1175/1300 pounds tension is attained. Check to ascertain that all
flying wire end fittings have proper engagement. Lock all check nuts and recheck all safeties.
Wing Installation and Rigging
Place a padded support where the outboard end of the upper wing panel will be. Slide upper wing into
center section attach fittings using care to enter the pitot tubes and harness into the proper place. Install
wing attach bolts. Place a padded support where the outboard end of the lower wing will be. Slide the
wing into place being sure to enter the aileron control rod into place. Install wing attach bolts. Install the
landing wires being sure to have both end fittings equally engaged and adjust both wires equally to obtain
2 degrees of dihedral. Install the center inter plane strut. Adjust front inter plane strut to length required
to hold upper wing at 0 degrees incidence measured on lower surface at the strut points between the
spars to match the center section and then install. Adjust rear inter plane strut to hold lower wing at 0
degrees incidence measured on the lower surface at the strut points between the spars to match the
lower surface at the butt rib between the spars and then install. Install the wings on the other side using
the same procedure.
Install all three flying wires on each side being sure to have both end fittings equally engaged. Adjust all
flying wires to the point where tension is just starting to build up. At this point, adjust the center flying wire
to 1175/1300 pounds tension. Then adjust rear flying wire to 1175/1300 pounds tension. Now adjust
front flying wire to 800/900 pounds tension. Check the tension in both landing wires and adjust by
decreasing the tight wire and increasing the lower tensioned wire equal amounts until they are equal in
tension. Recheck the flying wires to be sure they are still within tension tolerance. Recheck dihedral and
incidence angels, making any final adjustment necessary. Check to ascertain that all flying wire and
fittings have proper engagement. Tighten all check nuts and then recheck all cotter pins, lock nuts, check
nuts, etc., for security and proper safeties.
Aileron Control Installation and Rigging
Block all ailerons in neutral position (aileron trailing edge aligned with the wing trailing edge). Block
control stick in neutral (centered between cockpit sides). From underneath the airplane through the belly
access panel, adjust the aileron push rod end fittings until the rod end fitting hold aligns with the control
rod fittings and safety the bolts with a cotter pin. Tighten the check nuts on the push rod end fittings.
Next adjust the aileron interconnect strut end fittings for equal engagement of both ends and a length to
provide a slip fit of the end attachment bolts through the aileron fittings with the strut in position. Be sure
to install 11688 bushing in each fitting and install. Tighten all check nuts and recheck all safeties.
Remove the blocking from the ailerons and control stick. Check the aileron control system for free
movement and proper operation. Set the up angular travel of both lower ailerons from neutral (trailing
edge of aileron and wing aligned) to full up at 25 +/- 3 degrees. This is accomplished by changing the
length of the stop tab located on the lower wing skin next to the aileron bell crank as required.
Lubricate the various working parts of the control system using engine oil. Controls will naturally be
rather stiff on a new airplane until they have been worked in for a few hours.
Complete the installation of pitot and static lines, electrical harness, fuel system, fairings and access
panels and covers.
If properly rigged, the airplane should fly in a normal course with “hands off” for an indefinite period in
smooth air. However, if it should prove to be a little right wing heavy, for instance, this can be corrected
by lengthening slightly the right rear inter plane strut, or if left wing heavy, the left rear strut.
