1. An aircraft comprising:
a motor,
a primary structure of a pylon and an engine attachment system connecting the primary structure and the motor, said primary structure having a lower face and right-hand and left-hand lateral faces positioned on either side of a vertical median plane (PMV),
the engine attachment system comprising:
an L-shaped shackle, positioned in a transverse plane, which has first and second ends and an intermediate zone,
a first engine connection pin connecting the first end of the first shackle and the motor,
a second shackle, positioned in a transverse plane, which has first and second ends,
a second engine connection pin connecting the first end of the second shackle and the motor,
a right-hand interface connected to the right-hand lateral face of the primary structure,
a left-hand interface connected to the left-hand lateral face of the primary structure,
a first interface connection pin connecting the second end of the first shackle and a first interface among the right-hand and left-hand interfaces,
a second interface connection pin connecting the intermediate zone of the first shackle and the first interface,
a third interface connection pin connecting the second end of the second shackle and a second interface, which is different from the first interface, among the right-hand and left-hand interfaces,
a right-hand emergency connection pin cooperating with the right-hand interface and the motor,
a left-hand emergency connection pin cooperating with the left-hand interface and the motor,
wherein each right-hand or left-hand interface comprises front and rear arms positioned in transverse planes, parallel to each other and slightly spaced apart, and a right-hand or left-hand base connecting the front and rear arms, said right-hand or left-hand base being connected to the primary structure by a connection element.
