A fan assembly 1 for a gas turbine, the assembly comprising: a fan surrounded by a fan casing 2; a resilient, radially flexible containment material 4 wrapped around the outside of the fan casing 2 for containing a fan blade which has breached the casing 2 during a fan blade-off event, and a retaining cable arrangement for resisting separation of a first portion of the casing 10 from a second portion of the casing 12 as a result of said breach occurring between the first and second portion; wherein the cable arrangement comprises: a retaining cable 14 on the outside of the containment material 4, secured between the first and second portion 10, 12 of the casing, the retaining cable 14 being sufficiently radially compliant for radial deflection to accommodate radial flexing of the containment material 4 caused by impact of said fan blade in between the first and second portion 10, 12; and a locking arrangement 30 operable to subsequently lock the retaining cable 14 between the front and rear portions 2a, 2c of the casing whereby separation of the front and rear portions is resisted by tension in the locked cable 14.
