Which of the following best describes a correct use for surface tape?

• A. Over rib stitching.
• B. Over the leading edge only.
• C. Over rib stitching and sewed seams, over overlapped edges, around corners, and along the leading and trailing edges.
• D. Only on the trailing edge.

Answer: (C)

Surface tape is used to seal and smooth fabric joints on fabric-covered aircraft surfaces, creating a continuous, aerodynamic skin and protecting seams from moisture and wear. Because joints, overlaps, and edges are potential sources of leakage and fabric fatigue, the tape should be applied wherever these features occur: over rib stitching and sewn seams, over overlapped edges, around corners, and along both the leading and trailing edges. This broad application ensures all seams and edgestones are protected and the surface remains smooth and airtight. Limiting tape to just one area would leave other joints exposed and more prone to damage or moisture intrusion.
