Perform a model based system engineering gap analysis of a Structural Damage Detection System complementary to Structural Health Management based on selected generic use cases covering E2E product life cycle (design, development, manufacturing, integration, deployment and operation).

The nature of SHM data differs from that seen in traditional NDE applications in that the position of SHM sensors is fixed and that SHM data will be available much more frequently (if not continuously) over time.

This SAE Aerospace Information Report (AIR) provides information regarding guidance when utilizing an SHM system for “airworthiness credits”. This document is applicable to civil fixed-wing aerospace airframe structural applications where stakeholders are seeking guidance on the approvals of structural health monitoring (SHM) technologies for aircraft health management applications. While this initial guidance is from the United States’ Federal Aviation Administration (FAA), Technical Innovation Policy Branch, other regulatory agencies may elect to add requirements as needed. Future revisions to this document could include the guidance from other regulatory agencies. This document does not teach how to design an SHM function, how to do a safety or risk analysis, prescribe hardware or software assurance levels, or answer the question “how much mitigation and evidence are enough.”

The document describes typical processes with examples on how to manage reliability assessment hardware and software used on structural health monitoring systems, and for structure health management solutions. It addresses reliability assessment guidelines from design phase, manufacturing, assemblies, installation, considering installation and environmental conditions. Link between Quality system and reliability assessment is developed

This document will provide topics and possible content for industry to use in setting up training programs for personnel involved in deployment of SHM systems. The two primary parts of the training are: installation and usage.
