Abstract: A C-shaped connection assembly transmits loads in a load plane between a first and a second wing element. The connection assembly comprises a first and a second L-shaped load-bearing device. Each load-bearing device comprises a joint region and two legs extending parallel to the load plane and away from the joint region towards respective end regions. One leg of the first load-bearing device extends parallel to one leg of the second load bearing device. These legs are connected to one another. Two coupling portions which connect the connection assembly to the second wing element are formed in the respective joint regions of the load-bearing devices. Two further coupling portions which connect the connection assembly to the first wing element are formed in respective free end region of the load-bearing device and the joint region of the second load-bearing device.
