<p>PROBLEM TO BE SOLVED: To provide a blade inspection system capable of positioning a tip of an insertion part of an endoscope at a position at which a region to be observed of a blade is imaged in short time after the insertion part is inserted into an external access port of an engine.SOLUTION: In a blade inspection system 1, each of endoscope guide devices 3 and 4 for a bore scope 2 includes: an insertion part guide tube 21 guiding an insertion part 11; and a first fixation part 24 provided on the insertion part guide tube 21 for fixing the insertion part guide tube 21 at a corresponding external access port OAP. The endoscope guide devices 3 and 4 differ in a length of an extension part of the endoscope guide device 3 or 4 extending from the corresponding external access port OAP so that a position at which an observation optical system of the insertion part 11 observes a predetermined region of a blade can be set to a position preset per corresponding external access port OAP when the insertion port 11 is attached into the insertion part guide tube 21.</p> |
