A Cessna 208B Grand Caravan, N732MD, was substantially damaged at Chicago O'Hare International Airport (KORD), Illinois. The two pilots and nine passengers were not injured.
The pilot in command and 9 passengers were on board the airplane, and the second in command was outside on the right side of the airplane; adjacent to the passenger door and ventral stairs. A passenger in the last row of the airplane asked the second in command to assist her with her seatbelt, at which time the second in command climbed up the stairs into the airplane. At the same time, the gate agent removed the tail stand from the airplane, without communicating with the flight crew.
A passenger in row 3 then stood up to hand a carry-on bag to the second in command so that it could be stowed in the cargo compartment. As the passenger stood up and stepped towards the back of the airplane, the airplane titled backwards and the tail struck the tarmac. The pilot in command ensured that everyone was okay and then asked passengers to move forward in the airplane in an effort to bring the nose of the airplane back down. The pilot in command, second in command, and passengers disembarked from the airplane without further incident.
An examination of the airplane revealed substantial damage to the bulkhead in the tail section of the airplane. An examination of the airplane and remaining systems revealed no anomalies.

Probable Cause:

PROBABLE CAUSE: "The gate agent’s premature removal of the tailstand without confirming with the flight crew that it was safe to remove, which allowed the airplane to tilt backward when a passenger stood up and stepped toward the back of the airplane."
