Each WSC aircraft should have a specifi c routine prefl ight  inspection checklist, but the following can be used as an  example and guideline.  Start with the nose. Inspect the nose plates and the attachment  to the leading edges and keel. Ensure the nose plates are not  cracked and the bolts are fastened securely. Check the wire  attachments, top and bottom. Inspect the control frame, down tubes and control bar for  dents and ensure they are straight. Inspect the control frame  attachment to the keel. Inspect the control bar to down tube  brackets and bolts.  [Figure 5-43]  Inspect fore and aft fl ying  wire condition, attachment to the keel, and the lower control  bar corner brackets. Inspect the left side flying wire attachment to the control  bar bracket and condition of the flying wire up to the wing  attachment. Examine the flying wire attachment to the leading  edge and crossbar, as well as all hardware at this crossbar and  leading edge junction.  [Figure 5-44]  Inspect the condition of  the crossbar and the leading edge from the nose to the tip. Any  discrepancies or tears in the leading edge fabric must lead to  more detailed investigation of the leading edge spar itself. Move along the trailing edge of the wing, inspecting the  condition of the trailing edge and the tip batten attachments  back to the keel.  [Figure 5-46]  Inspect the sail material,  top and bottom, on the wing. Note that the trailing edge is  Inspect the tip area, including the washout strut and general  condition of the tip. If it is a double surface wing, look inside  the tip and examine the inside of the wing and its components.  [Figure 5-45] From the tip, inspect the surface condition of the fabric.  Generally, if the fabric has not been exposed to sunlight for  long periods and stored properly, the wing fabric should stay  in good shape.  Wing Inspection Figure 5-44.
