1. A device for mounting an aircraft tail wheel on an attaching arm made integral with said tail and for preventing loss of aircraft control in a ground loop, wherein the device includes:

a support plate including a vertical aft bore and a vertical fore bore upstream of the aft bore, the fore bore offset from and parallel to the aft bore;

a vertical aft articulation shaft mounted in the aft bore and attached to the attaching arm; and

a vertical fore articulation shaft mounted in the fore bore upstream of the aft articulation shaft, offset from and parallel to the aft articulation shaft, and attached to a fork receiving the freely rotating tail wheel;

wherein an axis of the aft articulation shaft intersects with a horizontal axis of rotation of the tail wheel; and

wherein the support plate is connected to a rudder bar arranged around the aft articulation shaft to steer the support plate with respect to the aft articulation shaft.

2. The mounting device according to claim 1 , wherein the support plate includes a lock that releasably locks the articulation shaft of the fork.

3. The mounting device according to claim 2 , wherein the lock can be operated from the aircraft cockpit.

4. The mounting device according to claim 3 , wherein the lock includes a pin mounted against a return spring and mounted to slide freely in a housing of the plate and to be engaged, in the locking position, in a part of the fork with said pin being connected to a control cable operable from the cockpit.

5. The mounting device according to claim 1 , wherein the aft articulation shaft is freely rotatable with respect to aft sealed running components and the fore articulation shaft is freely rotatable with respect to fore sealed running components.
