Abstract
An assembly and method for attaching an engine pylon to an aircraft wing. The method may include attaching a first forward wing-mounted fitting to the pylon at a first side of the pylon between upper and lower spars of the pylon and attaching a second forward wing-mounted fitting to the pylon at a second side of the pylon between the upper and lower spars of the pylon. The second side of the pylon is located opposite of the first side of the pylon. Mechanical attachment devices may be inserted through holes on the sides of the pylon aligned with holes formed through the forward wing-mounted fittings. The mechanical attachment devices may be made of steel and the forward wing-mounted fittings may be made of composite or aluminum material.

13. A method of attaching an engine pylon to an aircraft wing, the method comprising:
-
inserting at least one first mechanical attachment device through attachment holes of a first forward wing-mounted fitting and through a first pylon side hole formed through a first side of the pylon between upper and lower spars of the pylon, wherein the first forward wing-mounted fitting is attachable to or integrally formed with a front spar of the wing; inserting the at least one first mechanical attachment device or at least one second mechanical attachment device through attachment holes of a second forward wing-mounted fitting and through a second pylon side hole formed through a second side of the pylon, opposite of the first side, and between the upper and lower spars of the pylon, wherein the second forward wing-mounted fitting is attachable to or integrally formed with a front spar of the wing; and attaching a rear wing-mounted fitting to a rear end of the pylon. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method of attaching an engine pylon to an aircraft wing, the method comprising:
-
inserting at least one first mechanical attachment device through a side attachment hole of a first forward wing-mounted fitting, through a first pylon side hole formed through a first side of the pylon between upper and lower spars of the pylon, and through a first bore formed into a support bulkhead of the pylon, wherein the first forward wing-mounted fitting is attached to or integrally formed with a front spar of the wing, wherein the first side attachment hole, the first pylon side hole, and the first bore are axially aligned along an axis extending through a width of the pylon; inserting the at least one first mechanical attachment device or at least one second mechanical attachment device through a second attachment hole of a second forward wing-mounted fitting, through a second pylon side hole formed through a second side of the pylon, opposite of the first side, and between the upper and lower spars of the pylon, and through a second bore formed into a support bulkhead of the pylon, wherein the second forward wing-mounted fitting is attached to or integrally formed with a front spar of the wing, wherein the second side attachment hole, the second pylon side hole, and the second bore are axially aligned with the axis extending through the width of the pylon; attaching a center wing-mounted fitting located between the first and second forward wing-mounted fittings to the pylon at or proximate to the first and second sides of the pylon by way of center attachment links; inserting a failsafe catcher pin integrally formed with and protruding from a rear wing-mounted fitting attached to the wing into a failsafe catcher hole formed through a rear linking attachment plate fixed at an end of the pylon; and mechanically fastening the rear wing-mounted fitting with the rear linking attachment plate by inserting mechanical fasteners through attachment holes formed through the rear linking attachment plate that align with at least one attachment hole formed into the rear wing-mounted fitting when the failsafe catcher pin is inserted in the failsafe catcher hole.
