The mounting apparatus of claim 7, wherein the thrust assembly further comprises an elongated thrust link assembly having a pin-receiving hole at an end, the pin-receiving hole axially aligned with the pin receiving hole of the mounting tongue. 9. The mounting apparatus of claim 8, wherein the aft mount and the link assembly are symmetric about an axis parallel with the major axis of the aircraft engine and the forward mount is symmetric about an axis transverse to the major axis of the aircraft engine. 10. The mounting apparatus of claim 1, wherein the aircraft engine attachment assembly of the forward mount comprises a clevis, lug, ball joint, or rod end. 11. The mounting apparatus of claim 1, wherein the aft mount further comprises an aircraft engine attachment assembly including a clevis, lug, ball joint, or rod end. 12. A mounting apparatus for an aircraft engine that provides load path redundancy, the mounting apparatus comprising: a forward mount assembly operable to attach to the aircraft engine and a pylon and including spaced-apart walls defining a channel, each wall including a pin-receiving hole;a thrust fitting assembly configured to be positioned between the forward mount and the aircraft engine, the thrust fitting assembly including a pin-receiving hole and a forward mounting flange, the forward mounting flange positioned within the spaced-apart channel of the forward mount assembly and having a pin-receiving hole axially aligned with the pin-receiving hole of the forward mount assembly;a first fastener for securing the thrust fitting assembly in the forward mount assembly and positioned within the pin-receiving holes of the forward mount assembly and the pin-receiving hole of the forward mounting flange;a thrust link assembly pivotally connected to the thrust fitting assembly at a first end of the thrust link assembly; andan aft mount assembly operable to attach to the aircraft engine and pivotally connected to the thrust link assembly at a second end of the thrust link assembly with a second fastener, the aft mount assembly including two upstanding spaced-apart flanges defining a channel, each of the upstanding flanges having an axially-aligned pin-receiving hole. 13. The mounting apparatus of claim 12, wherein the forward mounting assembly further comprises: an elongated arcuate yoke assembly; anda forward mounting link assembly. 14. The mounting apparatus of claim 12, wherein the first fastener is a bolt, a pin, a lug, or a screw. 15. The mounting apparatus of claim 12, wherein the second fastener is a bolt, a pin, a lug, or a screw. 16. The mounting apparatus of claim 12, wherein the thrust link assembly includes a clevis, lug, ball joint, or rod end at the first and second ends. 17. The mounting apparatus of claim 12, wherein the forward mount assembly further comprises a plurality of attachment points for the aircraft engine. 18. The mounting apparatus of claim 12, wherein the aft mount assembly further comprises a plurality of attachment points for the aircraft engine. 19.
