Abstract: An assembly of an engine mounting pylon with an aircraft engine, by virtue of a front engine mount rigidly secured to an aircraft primary structure, including a body partially fitted into the primary structure. The body includes, on its front face, a first and second pair of branches. The branches of the two pairs all extend forwards and parallel to the median vertical plane. The body includes a lower face facing the engine and a stud located in the vertical median plane and articulated to the engine, a two-point straight shackle, inserted between the branches of the first pair of branches, being articulated, at one location, to the body via a first pivot pin and, at another location, to the engine via a second pivot pin. Each of the branches of the second pair of branches are articulated to the engine via the second pivot pin.
