CAUTION: Install castle nuts in this
section finger tight, to eliminate lateral play but allow freedom of
movement, then install the cotter pin.
Step 01:
Attach the F-1287D-L & R Clevis Plates together using the parts and
hardware called out in Figure 1. Pay attention to the orientation of the
clevis plates in relation to the F-1287C Link. Cleco the clevis plates
to the F-1287E Pushrod. pay attention to the orientation of the pushrod
in relation to the clevis plates. |
|
|
Step 02: Match-Drill the
holes in each of the F-128D-L & R Clevis plates into the F-1287E Pushrod
as called out in figure 1. Remove the clevis plates with the hardware
still attached. Clear away chips. |
|
|
Step 03: Clamp the F-1287F
Threaded insert into the curved end of the F-1287E Pushrod as shown in
Figure 1. Use a rivet or similar to align the holes in the threaded
insert with the holes in the pushrod |
|
|
Step 04: Match-Drill the
holes from the F-1287E Pushrod and the F-1287F Threaded insert into the
pushrod as called out in Figure 1. |
|
Step 05:
Rivet the F-1287D-L & R Clevis Plates to the F-1287E Pushrod using the
hardware called out in Figure 1. Apply pressure toward the clevis plate
while setting each rivet. Rivet the F-1287F Threaded Insert to the
pushrod using rivets called out in Figure 1.
Hereafter refer to
this as the Pushrod Assembly. |
|
|
Step 06:
Install the called out rod end bearing and jam nut into the F-1287F
Threaded insert per dimensions in figure 2. Achieve the dimension given
the rotate the bearing body to align with the centerline of the pushrod
Assembly as shown in Figure 2. |
|
Step 07: Thread the
jam nut onto the ES MSTS-T3_7A-2 Pitch Trim Servo shaft until it
contacts the pitch trim servo housing.
Thread the clevis rod end of the Pushrod Assembly onto the pitch trim
servo shaft until it contacts the jam nut. Back the clevis rod end off
one full turn. Tighten the jam nut against the clevis rod end.

|
Step 08: From below
the Stabilator Assembly, guide the rod end bearing of the Trim Servo
Assembly up between the stabilator main skins to the AST Assembly
control horns as shown in Figure 3. |
|
|
Step 09: Install the
F-1287A Servo Tray to the F-1211D Attach Brackets using the hardware
called out in Figure 3. Prior to Section 25 - Tailcone Attachment,
separate the legs of the cotter pin only enough to hold it in the hole
until final installation. Fully install this cotter pin after the
tailcone is attached to the fuselage. |
|
|
Step 10: Install the
rod end bearing to the AST Assemblies using the hardware called out in
Figure 3. |
