This SAE Aerospace Recommended Practice (ARP) defines the documentation, environmental considerations, test and evaluation criteria necessary to support certification of additive manufactured parts used on aircraft seats and associated furnishings. This document is to be used in conjunction with the existing applicable regulatory documents and requirements for parts which are used in low-criticality and non-critical applications.

This SAE Aerospace Recommended Practice (ARP) defines acceptable methods for determining the effect of disinfectants application to passenger and crew seating products in transport aircraft. This ARP selected a standard application process for all disinfectants in order to remove one variable from the investigation, which, at the time, was more concerned with the unknown effect of disinfectant chemicals on seat materials. The SAE Aircraft Seat Committee noted that most disinfectant manufacturers have their own application regimens to ensure the effectiveness of their product and that these differ from those defined in the ARP. Consequently, the standard application methodology defined in the ARP is not suitable for qualifying disinfectants, but is rather a standard method to compare the disinfectant’s behavior across a range of seat materials. Acceptance of individual disinfectants for specific application regimens is outside the scope of this ARP.

This Aerospace Recommended Practice (ARP) provides recommendations intended for standardization of safety lap belts without hindering the development of new, improved design. The purpose is not to specify the design methods or specific mechanism to accomplish the objectives.

This document applies to webbing used on occupant restraint systems in service on 14 CFR/CS part 23, part 25, part 27, and part 29 aircraft applications. The guidelines presented within this document are intended to be supplemental to the requirements supplied by the OEM in the CMM, ICA, or like document. In cases of conflict between this ARP and the OEM’s requirements, the requirements of the OEM shall be followed. The objective of this document is to establish practical guidelines to help operators in the determining if restraint webbing has reached the end of its service life. The recommendations contained herein are based on test data from in service restraint systems and the continued airworthiness guidelines recommended by restraint system OEMs.

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.

Part I of this document relates to the restraint systems for the flight deck crew. Part II considers restraint systems for flight attendants and other crew members. As applicable, the same criteria should be incorporated in both Part I and Part II installations. 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 and aft-facing seats. However, the design should 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.

In addition to those aspects of a passenger seat as comfort and appearance, the passenger seat, whether aft, forward or side facing, is the basic link that supports and ties the occupant to the aircraft structure. It is essential that the support and tie down functions be accomplished in a manner that will provide maximum safety during all normal conditions of flight, emergency flight maneuvers and crash landings, whether on land or water, and that these functions are not compromised to attain the comfort and appearance features.

This document outlines the evaluation and documentation appropriate when the components of an approved aircraft seat restraint system are replaced or modified by a party other than the Original Equipment Manufacturer of the restraint system.

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.

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.

This SAE Aerospace Recommended Practice (ARP) defines the test set-up requirements, general analysis procedures, and test report documentation for impact tests where photometric analysis of the high speed film or digital video will be required to obtain target paths (typically the Anthropomorphic Test Dummy (ATD) head path and knee path). Such tests support the requirements of AS8049 - Performance Standard for Seats in Civil Rotorcraft, Transport Aircraft and General Aviation Aircraft. These setup and analysis procedures are applicable to conventional, geometry based, two-dimensional analysis. If a more sophisticated technique that allows cameras to be installed at oblique angles for two or three-dimensional analysis is used, then the specific procedures required by that technique supersede any conflicting procedures contained herein.

Seat furnishings are installed around seats and are intended to enhance passenger privacy and comfort. They may have provisions for additional occupants to be seated when the aircraft is in-flight, but would not be occupied during taxi, take-off, and landing (TTL). This Aerospace Standard (AS) establishes the minimum design, performance and qualification requirements for seat furnishings with and without upper attachments (see Figures 1 and 2) to be installed in large transport category airplanes. This standard excludes seat furnishing designs that are directly attached to the seat assembly, for which AS8049 is the applicable standard. Integrated items (desk tops, cabinets, shelves, stowage areas, closeouts, dividers, etc.) connected to seat furnishings shall comply with the requirements of this AS as part of the seat furnishings.
