Abstract: Method and apparatus testing engine component, for blockage of one or more through-holes in a portion of a wall. The method including (i) providing a supply of test fluid, (ii) causing or permitting flow of test fluid to occur from first to second region, (iii) illuminating the second region with electromagnetic radiation to cause scattering of electromagnetic radiation by material exiting substantially non-blocked through-holes in wall portion having passed therethrough from the first to second side, (iv) detecting said scattering of electromagnetic radiation from said substantially non-blocked through-holes; and (v) comparing said detected scattering of electromagnetic radiation from said substantially non-blocked holes with known pattern of through-holes in component wall portion to determine the presence and/or location and/or identity of any blocked or partially blocked through-holes in component wall portion.
