3. Repair Data for the Flap Shells.
Figures 2 and 3 show the layers of glass/carbon fiber cloth in the flap shells. Use this data when you need to repair the flap.
The Figures show the main layers of cloth. The cross-hatching on the figure shows the orientation of the fibers. The orientation is also given in the related table. When you repair the flap, you must use the same type of cloth with the same fiber orientation.
The numbers in circles beside each drawing give the order in which the layers are applied (‘Stages’). The first stage is a layer of filler and is not shown. Stage 1 is the outer face of the shell.
Always do a burn test on a piece of composite from the damaged area before you do a repair. Refer to Section 51-20 for the burn test.
