RUDDER SYSTEM ASSEMBLY AND INSTALLATION
RUDDER FIT-UP
(BEFORE PRIMING OF FUSELAGE AND RUDDER FRAME)
1.
Rudder hinges must be secured in position. Temporarily bolt the rudder to
the fuselage. Adjust the rudder vertically to create a gap between the tip of
the vertical stabilizer and the overhang of the rudder of approximately
3/16”. Also, check that the rudder horns at the base of the rudder are
approximately in-line with the two threaded bushings for the rudder stop
bolts (bottom of fuselage) when the rudder is deflected. Refer to
FIGURE
01G-01
.
2.
Slide the hinge retaining collars against the hinges. The collars should be
positioned to allow free hinge movement with minimal play.
3.
Locate and drill a #30 hole on the interior side of each retaining collar
through the leading edge spar of the rudder. Rivet collars in position as
per parts manual.
4.
Remove rudder from fuselage. The rudder frame is now ready for prep
and priming. The rudder frame is ready for covering after priming. There is
no further assembly required.
PRE-COVERING ASSEMBLY
(AFTER PRIMING OF FUSELAGE FRAME/ BEFORE COVERING)
5.
The rudder cables, and pulleys at Station 7 should be installed before the
fuselage is covered. This will simplify final assembly. Refer to parts
manual and
FIGURE 01G-05
.
6.
Route the rudder cables between the tangs at Station 7 and bolt the
pulleys in place.
NOTE: The cables route on top of the pulleys.
Check that
the pulleys turn freely after installation.
7.
Route the Rudder Cables forward to Station 3. Roll up rudder cables, bag
and tape to a fuselage frame member. This will keep the cables off the
fabric when covering and painting.
