Abstract
A fan case assembly extend along and around a center axis. The fan case assembly may comprise a barrel extending along and around the center axis, the barrel configured to fasten to a flange of an engine case. The fan case assembly may comprise a fan track liner disposed radially inward of the barrel and a containment hook, wherein the containment hook is a discrete component separate from the barrel. The containment hook may include a front segment configured to fasten to the flange, and an axial segment disposed radially inward of the barrel. The axial segment may extend between the flange and the fan track liner and the front segment may extend radially outward from an end of the axial segment. The containment hook may also include a protruding segment extending radially inward from the axial segment.
