Scope
This SAE Aerospace Information Report (AIR) provides guidance on the definition, development, integration, qualification/certification, and deployment of Structural Health Monitoring (SHM) technologies applied to commercial and military rotorcraft. Increased implementation of SHM is believed to have numerous potential benefits, including enhanced operational safety and reduced maintenance burden. The focus is on augmenting ARP6461 to address specific unique aspects of implementing SHM on rotorcraft without unnecessarily duplicating guidance already contained in the ARP that is generally applicable to both fixed-wing and rotary-wing aircraft.
For the purpose of this document, SHM is defined as “the process of acquiring and analyzing data from on-board sensors in order to determine the health of a structure”. Note that this is irrespective of whether the on-board sensors are a permanent or temporary installation. On-board sensors could include any presently installed aircraft sensors as well as new sensors to be defined in the future. Interrogation of these sensors could be done on-board during flight or off-board using ground support equipment during maintenance activities. It is assumed that the primary user of SHM in the near term will be the maintenance and operations crew. This document does not include guidance on SHM business case analysis nor display of health state or recommendations to the flight crew in real-time.
Rationale
Rotorcraft manufacturers, operators, and regulatory agencies will be able to utilize this AIR to link existing resources, including ARP6461, to Structural Health Monitoring (SHM) applications in rotorcraft. Operating environment and subsystem architecture common for rotorcraft will be in the forefront of the enclosed guidance with intention of bridging any existing gaps between generic documentation and rotorcraft.

Issuing Committee
Aerospace Industry Steering Committee on Structural Health
The scope of the committee is to accumulate, develop and disseminate SHM system technology and experience relating to the following groups -- a. Civil fixed and rotary wing air vehicles; b. Military fixed and rotary wing air vehicles; and c. Unmanned fixed and rotary wing air vehicles.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
