Abstract
A securing system is provided for securing a component to a gas turbine engine casing. The system has a core engine casing formed from a front casing portion and a rear casing portion. The casing portions have respective casing flanges at which the casing portions are detachably joined together. The system further has a component flange extending from a component. The component flange is configured so that, when the casing portions are joined together, the component flange is trapped between the casing flanges. One of the casing flanges projects inwards from the casing to form an airtight seal with the component flange on the inside of the casing. The other of the casing flanges projects outwards from the casing to form an airtight seal with the component flange on the outside of the casing.
