Guidelines for Implementation of Structural Health Monitoring on Fixed Wing Aircraft
|Publication Date:||1 August 2021|
This document is applicable to civil aerospace airframe structural applications where stakeholders are seeking guidance on the definition, development, and certification of structural health monitoring (SHM) technologies for aircraft health management applications.
Inputs to the structural health management are obtained from SHM equipment and/or from onboard sensors, delivering the detection and characterization of damage, load, or environmental parameters for operational and damage monitoring.
For the purpose of this document, SHM is defined as "the process of acquiring and analyzing data from on-board sensors to characterize the health of a structure." The suite of on-board sensors could include any presently installed aircraft sensors, as well as new sensors to be defined in the future.
The document has these major purposes:
• Provide guidance on the implementation of SHM in aircraft applications to assist developers in specifying the measurements, accuracy, reliability and other requirements of the system to be designed.
• Provide information on structural maintenance practices and provide guidance on how SHM can be incorporated within or as modifications to current maintenance and airworthiness documents.
• Standardize and harmonize worldwide understanding about SHM (including terminology).
• Provide basic requirements to guide SHM technology development.
• Recommend certification matters that are relevant to SHM.
