English to French Other Aerospace / Aviation / Space MMoteurs 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 !
N. B. : Je vais ouvrir une autre question pour la fin de la phrase.
