A fan casing assembly for a gas turbine, the assembly having a fan casing for surrounding a fan, a resilient, flexible containment material around the outside of the fan casing for containing a detached fan blade that breaches the casing during a fan blade off event, and a retaining cable arrangement for resisting separation of a first and second portion of the casing as a result of the breach. The cable arrangement includes a continuous length of retaining cable extending around the fan casing on the outside of the containment material, the retaining cable being slidably or rollably secured to each of the first and second portions at a plurality of positions around the fan casing to form respective cable spans between the casing portions, there being sufficient overall slack in the cable for accommodating radial flexing of the underlying containment material upon impact of the detached fan blade. |
