Preheat your air fryer to 380 degrees Fahrenheit.
In a medium bowl, toss the chicken pieces in the avocado oil until well coated.
In a separate small bowl, stir together the cumin, garlic powder, smoked paprika, chili powder, onion powder, salt, black pepper, and lime zest. Pour this seasoning mixture over the oiled chicken and toss until every piece is evenly coated.
Once the air fryer is preheated, lightly spray its basket with cooking spray. Carefully arrange the seasoned chicken pieces in a single layer, ensuring they do not overlap.
Air fry for 10-12 minutes, flipping the chicken halfway through the cooking time. Continue until the chicken is golden brown, crispy, and cooked through, reaching an internal temperature of 165 degrees Fahrenheit (74 degrees Celsius).
