An upper pylon element suspended to a flexmount member to be attached to a supporting structure, includes a suspension device having a first hook device arranged to cooperate with an attachment device on a lower pylon element, and a second hook device for suspension of the fan duct, the suspension device having a first operating state in which the first hook device is coupled with the attachment device on the lower pylon element thereby to suspend the lower pylon element to the upper pylon element and a second operating state in which the first and second hook devices are disengaged from the corresponding attachment device; a locking unit arranged when it is operated, to lock the lower pylon element to the core cowl; and a drive unit to actuate the suspension device and the locking unit from one operating state to the other.
