Rivet bottom flap ribs

Clecod the flap ribs in the flaps skins and riveted the bottom flanges of the ribs. Since the flaps need a twist to follow the wing wash out I did not rivet the other holes.

Rivet the rib 4 assembly:

The holes of nose rib 1 didn’t align with the holes in the skin (this situation is same on both flaps):

Inside photo of misalignment:

I reamed these holes to accept 4 mm rivets:

1 hole in the skin is just next to the flange of flap rib 2:

Not 100% trailing edge, I will need to adjust this when final riveting:

1 flap ready:

Cleco’s in for final check:

Second flap ready:
