horn attach holes, the holes for the mass balance weight attach at the
elevator tips and the 3 servo attach holes on top of the right elevator
(through welded tangs).
22.
Cut out the fabric inside the trim exit ring on the right elevator bottom side
using a sharp blade or utility knife.
23.
Attach both elevator horns to the elevators as per parts manual. For
orientation of horns, refer back to
FIGURE 01C-05
.
NOTE: The lower hole
of the horns must be drilled out to 1/4” (tight fit).

Install the trim servo in the right elevator. The servo is mounted by 3
screws. The screws enter the elevator from the topside through the
covering.
25.
Trim the trim exit cover (thermal formed fairing) to fit the glued on exit ring.
26.
Drill #40 through the 14 dimpled hole locations in the exit fairing.

Place the exit fairing centered on top of the exit ring. Refer to
FIGURE

drill # 40 through the exit ring. Cleco as you go.

Also, drill a hole for the trim wiring and slot fairing for easy removal without
the need for wiring disconnection.

NOTE: The servo arm runs
through the servo. As the front end retracts, the aft end extends out of the
servo. Both sides need clearance.
File exit ring if needed.
