Worn Lines

Some of the suspension lines on this main canopy have serrated edges, which indicates that it is time to reline the canopy. Different lines on the same canopy will wear at different rates. (The line at the top of this photo shows the most extensive damage). Generally, the lower part of the steering lines is where the most wear will occur, followed by the outside lines of each line group. As the slider grommets slide down the lines during deployment, the grommets generate heat, which wears out the lines over time. This heat can also cause significant shrinkage of Spectra® and Dacron® lines.

Having a line break during flight can be extremely dangerous, but it is a problem that you can help to prevent. Inspect your suspension and steering lines frequently, and don’t be afraid to ask a rigger to check them, as well. If the lines look fuzzy, frayed or discolored to the point that it is easily noticeable, it is probably time to have them replaced.
