Abstract: A method of inspecting a component comprising a cellular structure bonded to a carrier substrate to form a matrix of open-ended cells is described. The method comprises: submerging the component in an inspection liquid disposed within a pressure vessel; changing the pressure within the pressure vessel; withdrawing the component from the inspection liquid; and determining whether the cells of the component are filled with the inspection liquid. A corresponding inspection apparatus is also described.
