Described is a method of constructing the nozzle guide passage may include the steps of: providing a tubular pre-form having a plurality of layers of unconsolidated CMC fibres in which the internal walls of the tubular preform provide either working surfaces which define the main gas path walls of the assembled nozzle vane, or extraneous wall portions which do not provide working surfaces of the assembled nozzle guide vane arrangement; cutting the wall portions to provide one or more flaps which remain attached to the preform via a connecting portion of wall; and, displacing the flap from a first pre-cut position, to a second consolidation position to provide one or more ancillary features.
