Abstract

A method of inspecting a surface of a component, e.g. a turbine or compressor blade of a gas turbine engine. The method comprises (a) providing a probe for inspecting the component surface; (b) defining a reference surface that is offset from the component surface; (c) moving the probe so as to contact a plurality of discrete spaced apart inspection points on the component surface, each contact of the probe with an inspection point comprising a first movement of the probe from the reference surface to the inspection point; (d) retracting the probe from the component surface after each contact with an inspection point; and (e) inspecting the component surface each time the probe contacts an inspection point.
