Step 1:  Fabricate two F-1095C Trim Bellcrank Brackets from AA6-063X3/4X3/4 Aluminum Angle as shown in Figure 1.

It is critical that the 1/4 inch diameter hole and the 1/8 inch hole are exactly in line with each other.

 

Step 2:  Fabricate two F-1095G Trim Cable Anchor Brackets from AA6-1251X1 1/4 Aluminum angle as shown in Figure 2.

 
Step 3:  Fit the F-1095 Trim Servo Spacer to the underside of F-1095A Trim Mount Bracket as shown in Figure 2.
 
 

Step 4: Cleco the F-1095 Trim Servo Spacer to the F-1095A Trim Mount Bracket as shown in Figure 3. Cleco through four corner holes in the trim servo spacer.

Cleco the F-1095C Trim Bellcrank Brackets and F-1095A Trim Cable Anchor Brackets to the trim mount bracket as shown in Figure 4.

Match-Drill #30 the trim bellcrank brackets and trim cable anchor brackets using the holes in the trim mount bracket and trim servo spacer as drill guides. Double-check that the pairs of brackets are parallel to each other and to the edges of the cut-out in the trim mount bracket when match-drilling.

 

Step 5:  Cleco the F-1095F Trim Servo Spacer to the F-1095A Trim Mount Brackets as shown in Figure 3. Cleco through F-1095G Trim Cable Anchor Bracket attach holes leaving the four corner holes in the trim servo spacer.

Final-Drill the four corner holes in the trim servo spacer.

Remove the trim servo spacer from the trim mount bracket.

Machine countersink the eight #30 holes in the trim servo spacer for AN-426AD4 rivets. Countersink the LOWER SURFACE of the trim servo spacer. See Figure 3.

 

Step 6:  Run a #40 drill through the eight 3/32 inch diameter nutplate attach holes in the F-1095A Trim Mount Bracket.

Machine countersink the eight #40 holes in the trim mount bracket for AN426AD3 rivets. Counter sink the UPPER SURFACE of the trim mount brackets. See Figure 3.

Run a #30 drill through the 1/8 inch diameter holes in the close-out flanges in the trim mount bracket.

 
Step 7:  Deburr all holes and edges of the F-1095A Trim Mount Bracket, F-1095C Trim Bellcrank Brackets, F-1095F Trim Servo Spacer, and F-1095G Trim Cable Anchor Brackets.

Prime the trim bellcrank brackets and trim cable anchor brackets. All F-1095 Assembly parts are made from alclad material and may be primed if/as desired.

 

Step 8:  Rivet the F-1095C Trim Bellcrank Brackets, F-1095F Trim Servo Spacer, F-1095G Trim Cable Anchor Brackets, and K1000-08 Nutplates to the F-1095A Trim Mount Bracket as shown in Figure 5.

Install rivets through holes in the close-out flanges in the trim brackets as shown in Figure 5.

Step 1:  Run a #30 drill through all holes in the two F-1095D Trim Servo Links and the F-1-95E Trim Servo Link Spacer.

Deburr all holes and edges of the trim servo links and trim servo link spacer. Prime parts if/as desired.

Assemble the trim servo links and trim servo link spacer as shown in Figure 1.

 

Step 2:  Study Figure 2 until you understand the proper installation of the F-1095B Trim Bellcrank between the F-1095C Trim Bellcrank Brackets. Pay particular attention to the orientation of the trim bellcrank. Note that two thin washers are used as spacers between the trim bellcrank and the trim bellcrank brackets.

Temporarily install the trim bellcrank between the trim bellcrank brackets. Check for free rotation of the trim bellcrank with a minimum of side-play. The spacer washers may be replaced with thicker washers if there is excessive side-play.

Permanently install the trim bellcrank as shown in Figure 2.

Note: I ended up using just one spacer washer, two were to tight and nut would not go on to expose cotter pin hole properly. One worked just right and bellcrank moves freely. Remenber this is a castle nut and requires a cotter pin.

 

Step 3: Enlarge the four mounting holes in the Trim Servo by drilling #28. Figure 3.

Attach the F-1095D/E Trim Servo Link Sub-Assembly to the trim servo as shown in Figure 3.

 

 

Step 4:  Install the Trim Servo to the F-1095A Trim Mount Bracket and F-1095F Trim Servo Spacer as shown in Figure 4.

Attach the F-1095D/E Trim Servo Link Sub- Assembly to the F-1095B Trim Bellcrank as shown in Figure 4.

 

Step 5:  Install two CT-Q-43 Elevator Trim Cables through the F-1095G Trim Cable Anchor Brackets as shown in Figure 5.

Adjust the trim cable jam nuts so as to center the threaded portion of the trim cable on the trim cable anchor brackets.

 

Step 6:  Study Figure 5 until you understand the attachment of the threaded ends of the two CT Q-43 Elevator Trim Cables to the F-1095B Trim Bellcrank. Pay particular attention to the orientation of the bolts and the placement of the various washers.

Attach the threaded ends of the the CT-Q43 Elevator Trim Cables to the F-1095B Trim Bellcrank using the hardware called-out in Figure 5.
