Assess line strength

Depending on the age of your wing, we may remove an upper and main line to test their breaking strength.

Gliders may cease to be airworthy if their lines are no longer strong enough. Line strength reduces with age and use. We sample test Kevlar lines if your glider is more than two years old, and Dyneema after four. We may test younger gliders if the condition of the lines indicates significant use. Under European standard EN 926-1, the lineset must carry 14 times the maximum flying weight.
