Inspection Illustrations

Usually inspection illustrations are given by the Original Equipment Manufacturer (OEM) in the engine manuals and other publications to cover each part of the engine that needs inspection. Areas of inspected parts or assemblies are indexed on the Illustrated Parts Catalog, or other illustrated manuals. Each illustration shown the location of the area to be inspected, type of inspection, the method of performing the inspection such as type of dye penetrant to be used, etc. The technical manuals also indicate the preparation of the part as cleaning, paint removal, etc., before the part is to be inspected. When a particular type of inspection has been completed, reference is made to the next step of inspection. For example, if an FPI has been performed, it may be necessary to confirm any suspected or visible defect by visual inspection.
