Chop off both ends of each corn cob using a sharp knife to create flat, stable surfaces.
Stand one cob vertically on a sturdy cutting board, then carefully slice down through the center from top to bottom, rocking the knife gently to split it in half.
Lay each half flat side down on the board and cut lengthwise again to make quarters, then slice those pieces in half crosswise to create shorter rib-shaped sections.
Stir the melted butter and olive oil together in a small bowl, then brush the mixture evenly over all sides of the corn pieces.
Whisk the smoked paprika, garlic powder, onion powder, chipotle powder, sea salt, and black pepper together in another bowl, then sprinkle the seasoning evenly over the greased corn.
Arrange the seasoned corn ribs in a single layer in your air fryer basket, making sure they do not overlap, and cook at 400°F (204°C) for 6 minutes.
Flip the corn sections over and air fry for another 5 to 6 minutes until the kernels turn golden brown and the ribs curl outward.
Whisk the sour cream and lime juice together in a small bowl, drizzle it evenly over the hot corn ribs, then garnish the platter with the grated parmesan, cilantro, and fresh lime wedges. Enjoy!
