What is the purpose of rib stitching cord?
Seldom will you find a fuselage that needs any rib-lacing. Using a rib-lacing cord is the most common method of securing the fabric to the ribs of a surface. This cord is made out of polyester material and is extremely strong. A special needle is used to tie a specific knot to accomplish this step.
What is a rib in aircraft?

What is the minimum strength to which aircraft fabric is allowed to deteriorate before it is considered unairworthy?
