- the tower 13 also transmits to the structure of the aircraft the forces generated by the engine 10, and allows the flow of fuel, electrical, hydraulic, and pneumatic between the engine 10 and the engine. 'aircraft.
- the engine 10 is provided with a system for fixing the engine 10 to the pylon 13, interposed between the engine 10 and a lower face 15 of the pylon 13.
- the fastening system comprises a front engine attachment 16 and a rear engine attachment 17.
- L front engine attachment 16 links the fan casing 1 1 to the lower face 15 of the pylon 13, and the rear engine attachment 17 links the turbine casing 12 to the lower face 15 of the pylon 13.
- Figure 2 is a perspective view of the front engine attachment 16.

- the step of pre-positioning the engine with respect to the pylon comprises an additional sub-step between the sub-step of hoisting and the sub-step of positioning, offset along the X axis and forward of the assembly comprising the front engine attachment and the engine.
- the step of pre-positioning the engine with respect to the pylon comprises an additional sub-step before the sub-step of hoisting, of putting in place at least one wedge at the level of at least one of the links, to maintain in position the forward engine attachment relative to the engine, at an angle suitable for vertical hoisting performed during the sub-step of hoisting, continuously from the ground, until the first shear pin is substantially at the same height than the receiving cavity.
- the step of pre-positioning the engine with respect to the pylon comprises an additional substep after the sub-step of substantially parallel positioning, of removing the at least one shim.

- the front engine attachment 46 links the fan casing 1 1 to a front face 48 of the pylon 43
- the rear engine attachment 47 links the turbine casing 42 to a lower face 45 of the pylon 43.
- FIG. 5 and Figure 6 show the front engine attachment 46 used in the mounting method according to the invention.
- FIG. 5 shows the front engine attachment according to a YZ plane containing the Y and Z axes, fixed on the front face 48 of the pylon 43.
- FIG. 6 represents the front engine attachment 46 in an XZ plane containing the X and Z axes , linked to a coat rack 60, via a system of ball joints and connecting rods explained below.
- the coat hanger 60 is integrally fixed to the fan casing 41 of the engine 40.
- the front engine attachment 46 has an upper portion 64 and a lower portion 65. The upper portion 64 and the lower portion 65 extend along inclined planes. relative to each other.
- the upper part 64 is intended to be pressed against the front face 48 of the pylon 43, and fixed via a first shear pin 53 and a second shear pin 54.
- a first screw 84, a second screw 85, a third screw 58 and a fourth screw 59 is also used for fixing.
- the first shear pin 53 and the second shear pin 54 are shown inserted respectively in a first orifice 51 and a second orifice 52 passing through the front engine attachment 46 in the direction X.
- the first screw 84, the second screw 85, the third screw 58 and the fourth screw 59 are shown inserted in respectively a first hole 86, a second hole 87, a third hole 66, and a fourth hole 67 through the front engine attachment 46 in the direction X.
- the lower portion 65 of the front engine attachment 46 has four rods and four pairs of ball joints. Each pair of ball joints is associated with a rod. Only three pairs of ball joints and the three associated links are shown in FIG. 5. Each pair of ball joints comprises an upper ball and a lower ball. The upper ball joint serves to link the front engine attachment 46 to the associated link, and the lower ball joint serves to link the connecting rod associated with the coat rack 60.

- first hole 86, the second hole 87, the third hole 66 and the fourth hole 67 are then substantially at the same height as respectively the first hole 88, the second hole 89, the third hole and the fourth hole.
- FIG. 11 illustrates the various steps of a third embodiment of the method of mounting the motor 40 on the pylon 43 according to the invention.
- the third embodiment does not use the system of ball joints and rods for articulating the upper portion 64 relative to the lower portion 65 of the front engine attachment 46. However, it requires a tool on the ground allowing a shift of the motor 40 according to the direction X.
- Step 91 The motor 40 is hoisted vertically, in the Z direction, using halyard harnesses;
- Step 92 The motor 40 is shifted in the X direction and forwards. This offset is necessary because of the protrusions of the first shear pin 53 and the second shear pin 54.
- Step 93 The motor 40 is hoisted again vertically, in the Z direction to put the first shear pin 53 opposite the first breakthrough, and the second shear pin 54 next to the second pierced 82; - Step 94:
- the first shear pin 53 is inserted and adjusted in the first breakthrough, and the second shear pin 54 is inserted and adjusted in the second pierced 82;
- the first shear pin 53 and the second shear pin 54 are inserted beforehand and adjusted in the first hole and the second hole 82, respectively.
- the steps of the process are as follows:
- the motor 40 is hoisted vertically, in the Z direction, with hoisting harness; - The motor 40 is shifted in the X direction and forward;
- the motor 40 is hoisted again vertically, in the direction Z until the first shear pin 53 next to the first orifice 51, and the second shear pin 54 facing the second orifice 52;
- the first shear pin 53 is inserted and fitted into the first orifice 51, and the second shear pin 54 is inserted and fitted into the second orifice 52;
