Figure 2-10. Patch Repair of Stringer (For
Damage Less Than Two-Thirds of One Leg Width).
The repair just described is permissible when the damage does not
exceed two-thirds of the width of one leg of the stringer and is not
over 12 inches in length. When damage is greater than two-thirds of
the leg width, use the method shown in Figure 2-11.
A repair by
insertion, shown in Figures 2-12 and 2-13, is required if the damage
is so long that an unusual amount of material and work is required.
