SCOPE:

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.
