Step 01: Read all steps prior to construction.

NOTE: This section describes the Anti-Servo Tab ( AST ) construction for the left side. Construction for the right side is a mirror of the left, and should be done at the same time.

NOTE: The top surface and inboard end of the FS-1221L AST Skin can be identified by the AST Control Horn cutout, called out in Figure 4.
