Scope
This document is a guide to the application of magnesium alloys to aircraft interior components including but not limited to aircraft seats. It provides background information on magnesium, its alloys and readily available forms such as extrusions and plate. It also contains guidelines for “enabling technologies” for the application of magnesium to engineering solutions including: machining, joining, forming, cutting, surface treatment, flammability issues, and designing from aluminum to magnesium.
Rationale
This document is a guide to the application of magnesium alloys in aircraft seats. This document acts as a guide to support this technology by providing design engineers and project managers with guidelines for the appropriate use of magnesium alloys, advice of fabrication techniques that are unique to magnesium and an overview of the available forms of the material.

Issuing Committee
The Aerospace Council of SAE established the Aircraft Seat Committee (SEAT) in 1997 to address technical issues related to the design and/or performance of aircraft seating systems. The seating systems include crew, flight attendants, and passenger seats installed in Civil Rotorcraft, Transport Aircraft, and General Aviation Aircraft.
A list of the technical reports developed by the SEAT Committee can be obtained by searching on 'aircraft seat' and selecting 'standards', from the SAE Home Page. SEAT StandardsReference
* 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.
