Abstract: The invention relates to gas turbine engine structure, e.g. a bearing support structure (17, 18, 19) such as a Fan Hub Frame (17), comprising at least one casted part. The casted part extends at least partly around an axial opening (33) in the structure (17, 18, 19) for receiving a gas turbine engine shaft (15, 16). The structure comprises a conduit (29) for transport of a liquid phase fluid, e.g. oil or lubricant. The conduit (29) extends through a section of the casted part and a wall defining the conduit (29) forms a casted portion. One purpose of the invention is to provide a gas turbine engine structure which is adapted for an improved fluid distributing system, e.g. lubricant distribution during operation. By integrating the conduit (29) in the structure (17, 18, 19) may the conduit be designed such that a loss of pressure can be reduced during operation. More particularly, the invention creates conditions for achieving a desired performance concerning flow properties for the fluid within the system since it may be easier to allow larger cross sectional dimensions of the conduit (29) and thus less friction and pressure losses for the fluid flowing in the conduit (29). In addition, less work in fitting a conduit (29) into the structural unit is needed since it is already integrated at manufacturing.
