A fan jet engine mounted below and rearwardly of the wing of an aircraft. There are a pair of mounting arms which are connected to and extend rearwardly from the rear spar of the wing and connect to the fan case and the core engine case. The major portion of the cowling structure is mounted to slideways, so that the cowling structure can be moved rearwardly to expose the engine for service and repair. The thrust reverser is mounted to the rear of the cowling.
