Title:Guidance on Structural Health Monitoring for Aerospace Applications
Issuing Committee:G-11shm, Structural Health Monitoring And Mgmt (Aisc)
Scope: This document is applicable to civil and military aerospace airframe applications where stakeholders are seeking guidance on the development and certification of Structural Health Monitoring (SHM) technologies for Structural Health Management (SHMang) applications. 1.1Purpose The document has these major purposes:鈥rovide guidance for structural maintenance practices using SHM methods to facilitate the inclusion of these practices within maintenance and airworthiness documents鈥tandardize and harmonize worldwide understanding about SHM (incl. terminology)鈥rovide basic requirements to guide SHM technology development鈥rovide guidance on certification issues related to SHM1.2Field of ApplicationThe application of the document is to provide guidance for, but not limited to:鈥evelopment, maturation, design and certification of structural monitoring for application in civil air transport鈥odification of maintenance and management infrastructure to use and exploit SHM systems.鈥mprovement of maintenance practices by an alternative tools to conventional NDI that can satisfying scheduled and/or unscheduled maintenance tasks in a cost effective mannerNote: Although guidance such as this may be crucial to success, use of this guidance alone cannot be assumed to constitute regulatory agency acceptance. Any accepted use would be project specific following dialogue with the appropriate regulatory agency.
