The problem with this is at one point, you say that crippling will occur in the web of the beam but I only analyze crippling in the stiffeners of the ribs of the aircraft. This makes me a little confused. I currently work as a young stress analyst for an aerospace company in the US.

Crippling is considered a local buckling mode, and it can happen in any section. It is most critical in sections made of thin flanges like hat stringers, Z-Stringers, Angles, Tees, and the like. You can actually gain insight by considering each flange as a little plate, with simple, fixed, or free supports on each edge. Any section can cripple, however, longer sections will tend to undergo Euler buckling long before crippling occurs, while shorter sections will cripple first if the cross-section has thin flanges. Make sense?
