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 document provides guidance to promote dimensional compatibility between forward facing passenger seat systems in civil transport airplanes and child restraint systems developed primarily for use in automobiles.

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.

This SAE Aerospace Recommended Practice (ARP) documents a common understanding of terms, compliance issues, and occupant injury criteria to facilitate the design and certification of oblique facing passenger seat installations specific to Part 25 aircraft. The applicability of the criteria listed in this current release is limited to seats with an occupant facing direction greater than 18 and no greater than 30 degrees relative to the aircraft longitudinal axis. Later revisions are intended to provide criteria for other facing directions. Performance criteria for side facing seats installed with the occupant facing direction at 90 degrees relative to the aircraft longitudinal axis are provided in AS8049/1. Seats installed at angles greater than 30 degrees relative to the aircraft longitudinal axis must have an energy absorbing rest or shoulder harness. However, this document does not provide the criteria for oblique facing seats incorporating such rests.

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 such as comfort and appearance, the passenger seat, whether aft, forward, or side-facing, is the basic link that supports and ties the air transport passenger to the aircraft structure. It is essential that the support and tiedown functions be accomplished in a manner that will provide maximum safety and security during all normal conditions of flight, emergency flight maneuvers and crash landings, whether on land or sea and that these functions not be compromised to attain the comfort and appearance features.

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 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.

This SAE Aerospace Recommended Practice (ARP) provides guidelines for abuse load testing of a deployable Individual Video System (IVS). The abuse load testing defined in this ARP is intended to only address the evaluation of the deployable IVS regarding stowage of the system and injurious projections/protrusions as a result of passenger interaction with the video system. Other aspects of the video system design or qualification may require additional testing or analysis and are outside the scope of this ARP. This ARP is not intended to address customer satisfaction or reliability aspects of individual designs.
