A method enables a duct to be coupled to a gas turbine engine casing. The method comprises extending a first inner tube support member circumferentially around the duct, such that a radially inner side of the first inner tube support is against the duct, and wherein the first inner tube support member has a substantially curved cross sectional profile extending between the radially inner side of the first inner tube support, and a radially outer side of the first inner tube support. The method also comprises extending an outer tube support member circumferentially around the first inner tube support member such that the outer tube support member is against the first inner tube support member outer surface, and coupling the outer tube support member to the gas turbine engine casing.
