This document provides informational background, rationale and a technical case to allow consideration of the removal of the magnesium alloy restriction in aircraft seat construction as contained in AS8049B. The foundation of this argument is flammability characterization work performed by the FAA at the William J. Hughes Technical Center (FAATC), Fire Safety Branch in Atlantic City, New Jersey, USA. The rationale and detailed testing results are presented along with flammability reports that have concluded that the use of specific types of magnesium alloys in aircraft seat construction does not increase the hazard level potential in the passenger cabin in a post-crash fire scenario. Further, the FAA has developed a lab scale test method, reference DOT/FAA/TC-13/52, to be used as a certification test, or method of compliance (MOC) to allow acceptability of the use of magnesium in the governing TSO-C127 and TSO-C39C.
Other flammability studies are also cited in the AIR document to substantiate the FAA findings.
This document has been determined to contain basic and stable technology which is not dynamic in nature.

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.

* 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.
