The removable tail stand (called “tail prop”) which is used on ATR 72 aircraft to prevent the aircraft from tipping over in case improper loading or unloading causes a weight imbalance. The prop is manually removed by the flight mechanic or crew before flight. The integrated side stairway used for passenger boarding, at the rear of the cabin, can be seen on the left.
