A safe landing device used when a helicopter breaks down and shuts down in the sky above the land and the sea is composed of a top wing (1) installed above a rotor wing of the helicopter, a bottom wing (22) installed in an undercarriage and the like. A parachute is arranged in the top wing; during a normal flight, the top wing rotates along with the rotor wing; when the helicopter breaks down and shuts down, the parachute will be ejected out of the top wing in a second under the action of an ejection cartridge and be opened, and therefore the helicopter lands on the ground slowly. A water surface floating boat is arranged in the bottom wing; when the helicopter breaks down and shuts down in the sky above the sea, another ejection cartridge is started, the water surface floating boat will be immediately ejected out of the bottom wing, inflated and arranged below the helicopter in a cushioning mode, and therefore the helicopter lands in the sea safely.
