1. An aft part of an aircraft comprising: at least one engine assembly including a turbine engine and a turbine engine mounting pylon, the engine assembly being added onto a side of an aircraft structure;the pylon comprising a rigid structure offset radially from a longitudinal axis of the turbine engine along one direction of separation, and first attachment means for assembly of the turbine engine on the rigid structure and second attachment means fixed firstly to the rigid structure and secondly to the aircraft structure;the rigid structure comprising a longitudinal central box and a connection box carried by the central longitudinal box and projecting from it along a first direction of a line of separation from the turbine engine towards the rigid structure; andthe aircraft structure comprising a fuselage lateral extension projecting from the fuselage in a second direction along the line of separation, opposite the first direction,wherein one of the two entities among the lateral extension of the fuselage and the connection box is pressed into contact with the other entity, below it, the second attachment means being arranged between these two entities. 2. An aircraft comprising an aft part according to claim 1. 3. A method of assembly an aft part of an aircraft according to claim 1, comprising: lifting the engine assembly, so as to press one of the two entities into contact among the fuselage lateral extension and the connection box into contact with the other entity and below it; andthen mounting the second attachments means between the two entities. 4. An aft part according to claim 1, wherein the fuselage lateral extension comprises a plurality of first ribs;the connection box comprises a plurality of second ribs; andat least one of the first ribs is laid out in continuity of one of the second ribs, approximately in a same plane. 5. An aft part according to claim 4, wherein at least part of the second attachment means is fixed on the first and second ribs. 6. An aft part according to claim 4, wherein each first rib of the fuselage lateral extension is made in a single piece with a fuselage frame. 7. An aft part according to claim 1, wherein the second attachment means forms a statically determinate attachment system of the engine assembly onto the aircraft structure. 8. An aft part according to claim 7, wherein the second attachment means includes a plurality of mounts each including a rod resisting forces. 9. An aft part according to claim 1, wherein the second attachment means forms a statically indeterminate system for attachment of the engine assembly onto the aircraft structure. 10. An aft part according to claim 9, wherein the second attachment means includes a plurality of soft mounts each including a shock absorbing element made of rubber or elastomer.
