Riveted Left Wing Outboard Bottom skin IAW manual. This did in fact require bending the skin back but only for the last 4 ribs up to but not including the end rib. I riveted all the bottom skins while the wing was still held in the jig vertically rather than placing it on the bench as described in the manual. I liked this better since I secured the wing completely with ZERO twist and found no reason to unsecure the wing prior to completing all skin riveting. After the skin was complete I installed the two inboard ribs 1 at a time and riveted in place both top and bottom.
Dont forget to leave the bottom flap gap seal and bottom skin holes unriveted until the flap hinge is installed..I almost riveted these holes without the hinge in place....See photos....
