the liner element comprising a body portion (34) mounted in a recess in the casing and a wall portion arranged to form part of an inner wall of the duct,
the wall portion and the body portion being attached and defining a containment cavity (30a) therebetween for containment of a detached fan blade fragment in use,
wherein the wall portion comprises a moveable portion (36) which is movable between a first configuration in which it lies substantially flush with the inner wall of the duct, and a second configuration in which it provides an opening through which a fan blade fragment can enter the containment cavity. |
