English to French Other Aerospace / Aviation / Space Moteurs de l'Eurofighter Typhoon

Bonjour,

j'ai énormément de mal avec cette phrase qui décrit comment les moteurs de l'Eurofighter Typhoon tiennent en place :

"Once the engine is in place, it is essentially held into the aircraft purely and simply by one large nut on the top of the aircraft and two small pit pins that ***hang on to arms that hold off the rear fuse.*** And that’s it, that is purely it that holds the aircraft in."

Merci d'avance !
