ELEVATOR TO HORIZONTAL STABILIZER ATTACHMENT
NOTE:
The horizontal stabilizer should be attached to the fuselage and
bolts in both aft attach holes before attaching the elevator.
IMPORTANT:
The tailcone should be assembled and attached before the
Horizontal Stabilizer may be mounted
1.
Ensure the bronze flange bushings are in place on both the horizontal stabilizer
and elevator.
Ream the bushings to #11, if a 3/16” bolt will not insert into the
bushings.
2.
Slide the elevator into place on the horizontal stabilizer and use bent needle nose
pliers or similar to insert the bolts into the hinges. Take care not to ding or mar
the skins.
3.
Use the appropriate hardware to secure.
4.
Once the horizontal stabilizer/elevator is mounted to the tailcone, bolt the
elevator Push-pull Tube to the elevator horn as shown in the PARTS MANUAL
DRAWING. The Elevator Bushing Clip is easily installed from the lower side
using the “U” shape as a handle.
5.
Run the trim tab servo wires out the S-11 bulkhead, through the S-11 closeout,
through one of the holes in the leading edge of the elevator and finally through a
hole in the elevator spar. Refer to
FIGURE 08A-31A
. Connect, secure and
protect the wires as necessary. Ensure the elevator can move through its entire
range of motion without interference or damage with the servo wires due to
binding or chaffing.
