Note: 
Run clevis and jam nut all the way down to pushrod. Do not bend cutter pin prongs. These parts will need to be removed during the rigging process.
10. Temp install pushrod clevis to trim tab using pin, washer, and cotter pin.
11. Tape cotter pin in place so that it does not get lost.
12. Final install of pushrod clevis to trim tab using pin, washer, and cotter pin will be performed after Elevator Trim Rigging. (Inspect Pitch Trim Tab Rigging)

13. Verify and inspect Pitch Rigging. (Inspect Pitch Rigging)
14. Verify and inspect Pitch Trim Tab Rigging. (Inspect Pitch Trim Tab Rigging)
15. Install pushrod clevis to trim tab using pin, washer, and cotter pin.
16. Install components in the reverse order for removal.
Verification Method
