This aerospace recommended practice (ARP) addresses the care@ use@ and training required to employ an effective borescope inspection program. Five subsections are included that cover training@ storage@ preoperational inspections@ operation@ and postoperational care related to both rigid and flexible borescopes. Throughout this ARP@ proper borescope system nomenclature and terminology are utilized as specified in SAE ARP4022@ Borescope Inspection System Definitions. Purpose: This document is intended to provide borescope users guidance on methods of the maximum value out of their purchase of a borescope. By following these recommendations the quality of the inspections will be maintained and the service life of the borescope will be extended. A cardinal rule to be conveyed is that borescopes are delicate optical instruments and must be shipped@ stored@ used@ and cared for accordingly by trained personnel.
