An aircraft assembly comprising a wing and an engine attachment pylon fixed to the wing by an attachment comprising a first and a second front wing system cleat connecting a rigid structure of the attachment pylon and a front longeron of the wing. The first front wing system cleat comprises a first shearing pin oriented in the transversal direction to ensure take-up of forces exerted in the longitudinal and vertical directions of the pylon, and the second front wing system cleat comprises a second shearing pin oriented in the longitudinal direction to ensure take-up of forces exerted in the transversal and vertical directions of the pylon.
