A fan blade containment assembly 138 for a turbofan gas turbine engine comprises a generally cylindrical or frustoconical containment casing 140 having a rib 142 at its upstream end which extends circumferentially around the containment casing 140, and an intake casing 146 with a bulkhead 160 at its downstream end which extends circumferentially around the intake casing 146. The bulkhead 160 is directly fastened to the rib 142 of the containment casing 140, and curved ribs 156, 158 which extend circumferentially around the containment casing 140 are connected at their radially outer ends 166, 168 to the outer end 164 of the bulkhead 160. The ribs 156, 158 have spring fingers 172, 176 which allow for ease of assembly and removal. In an alternative embodiment, three curved ribs (156-158, Fig.5) are bonded or welded at their radially inner ends to the containment casing. A V-shaped projection 188 on door 186 engages in a V-shaped groove 184.
