Part I of this document relates to the restraint systems for the flight deck crew. Part II considers restraint systems for other crew members, including cabin attendants. The recommendations herein include coverage of such items as harness reels, shoulder harnesses, and safety belts. However, the intention is not to limit the design of restraint devices to these particular system components only. These recommendations apply primarily to forward-facing seats. However, the design must take into account the fact that loads may be applied from any direction and be of a magnitude at least as great as those specified in current FAR's.

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.
