The invention discloses a follow-up folding built-in airstair which comprises an outer cylinder, a first inner cylinder, a second inner cylinder, a first pedal, a second pedal, a third pedal, a first supporting rod and a second supporting rod. The upper end of the outer cylinder is hinged to an airplane, the left side of the lower end of the outer cylinder is hinged to the first pedal, the second inner cylinder can slide relative to the first inner cylinder, the first inner cylinder can slide relative to the outer cylinder, the second pedal is hinged to the right side of the lower end of the first inner cylinder, and the third pedal is hinged to the left side of the lower end of the second inner cylinder. The other end of the first supporting rod is hinged to the front side of the lower end of the first inner barrel. The other end of the second supporting rod is hinged to the front side of the lower end of the outer barrel. The folding and unfolding device has the advantages of being convenient to fold and unfold, small in occupied space after being folded, suitable for military aircrafts, capable of achieving rapid landing and landing, and capable of reducing work of ground crew.
