Safety Assessment of Transport Airplanes in Commercial Service

ARP5150B (Current)

8/15/2026

This document describes guidelines, methods, and tools used to perform the ongoing safety assessment process for transport airplanes in commercial service (hereafter termed “airplane”). The process described herein is intended to support an overall management of safety. It is associated with showing compliance to regulations and also establishing and meeting internal company safety standards. The methods identify a systematic means, but not the only means, to assess ongoing safety. While economic decision-making is an integral part of the safety management process, this document addresses only the ongoing safety assessment process. To put it succinctly, this document addresses the “Is it safe?” part of safety management; it does not address the “How much does it cost?” part of safety management. This document also does not address any specific organizational structures for accomplishing the safety assessment process. While the nature of the organizational structure is significant to the quality of a safety program, this document focuses on the functions to be accomplished and does not attempt to define what the structure should be. The intent is to leave the greatest amount of flexibility to the organizations that use this document.

Gaining Approval for Seats with Integrated Electronics in Accordance with AC 21-49 Section 7.b

ARP6448C (Current)

8/10/2026

This SAE Aerospace Recommended Practice (ARP) provides a framework for establishing methods and stakeholder responsibilities to ensure that seats with integrated electronic components (e.g., actuation system, reading light, inflatable restraint, in-flight entertainment equipment, etc.) meet the seat technical standard order (TSO) minimum performance standards (MPS). These agreements will allow seat suppliers to build and ship TSO-approved seats with integrated electronic components. The document presents the roles and accountabilities of the electronics manufacturer (EM), the seat supplier, and the TC/ATC/STC applicant/holder in the context of AC 21-49, Section 7.b (“Type Certification Using TSO-Approved Seat with Electronic Components Defined in TSO Design”). This document applies to all FAA seat TSOs C39( ), C127( ), etc. The document defines the roles and responsibilities of each party involved in the procurement of electronics, their integration on a TSO-approved seat, and the seat’s installation on an aircraft. Requirements for design and quality control and the methods for communicating design and change data between EMs and seat suppliers are defined such that standardization is possible across the industry to ensure continued airworthiness of TSO-approved seats with integrated electronic components. This document primarily focuses on correspondence between the seat supplier and the EM. Appendix A: Presents key characteristics of electronic components and guidance on how changes are classified per the requirements of Table 1 of AC 21-49. Appendix B: Provides an outline of a typical data approval process and the change management process between EMs and seat suppliers. Appendix C: While the responsibility rests solely with the seat supplier to ensure all TSO attributes identified in Table 1 of AC 21-49 are acceptable, Appendix C has been included to outline the process for delegating EMs authorization to assess the impact of changes on their equipment with respect to seat TSO attributes. This authorization will allow the classification of the change and the appropriate administration of the change by the EM via seat supplier delegation. Appendix D: Given the mix of business arrangements that can exist in the seat, in-flight, and aircraft procurement life cycle (buyer-furnished equipment, supplier-furnished equipment, customer-furnished equipment), there is discussion on the potential need for separate agreements between the EMs and seat suppliers to ensure binding flow down of design and quality control requirements. As such, a working together agreement (WTA) template is provided as Appendix D.

A Standardized Approach to On-Board Diagnostic (OBD) System Signal Classification and Dependency Analysis

HRCS-PRP0001 (Current)8/7/2026

Part of the legislated on-board diagnostic (OBD) certification process is focused on identifying and documenting serial data signals that are relevant from a legislated OBD perspective. OBD regulations and documentation required for vehicle certification today are becoming increasingly complex. The reason is that increasing numbers of electronic control units (ECUs) are being introduced that communicate with each other. Most of these ECUs are much more powerful in terms of computational power, enabling the implementation of much more functionality on a single ECU. Most of that new functionality is being developed in software. Where previously hard-wired sensors were dominating, nowadays software components take over interpreting and enhancing sensor inputs. This recommended practice (RP) describes a standardized approach to meet these requirements for such increasingly complex environments. Specifically, this RP outlines how to create a serial data signal input/output (I/O) disclosure list to identify, trace, and categorize serial data signals that are relevant to certification. Furthermore, this RP defines a standardized data exchange format that original equipment manufacturers (OEMs) and suppliers can use to exchange related information. In addition to the vehicle certification context, we see a benefit in applying the described methodologies in other contexts, such as the usage of serial data signals within non-emissions-related and/or safety-critical systems.

Defining and Measuring Factors Affecting Helicopter Turbine Engine Power Available

ARP1702B (Current)

6/29/2026

This SAE Aerospace Recommended Practice (ARP) identifies and defines a method of measuring those factors affecting installed power available for helicopter powerplants. These factors are installation losses, accessory power extraction, and operational effects. Accurate determination of these factors is vital in the calculation of helicopter performance as described in the RFM. It is intended that the methods presented herein prescribe and define each factor as well as an approach to measuring said factor. Only basic installations of turboshaft engines in helicopters are considered. Although the methods described may apply in principle to other configurations that lead to more complex installation losses, such as an inlet particle separator, inlet barrier filter (with or without a bypass system), or infrared suppressor, specialized or individual techniques may be required in these cases for the determination and definition of engine installation losses. Some rotorcraft may use an alternate source of propulsion system power to supplement engine output shaft power delivered. If RFM performance includes the contribution of a Supplemental Power Unit (SPU), then the installed power available of the SPU should also be defined and measured, for which the power loss factors and methods described in this document may be applicable.

Guide for Conducting an HIRF and Lightning Safety Assessment (HLSA)

ARP8482 (Current)

6/15/2026

Highly integrated electrical and electronic systems that perform functions within an aircraft may have potential failure conditions during and after exposure to the High-Intensity Radiated Fields (HIRF) or lightning environments. It is therefore necessary to conduct an HIRF and Lightning Safety Assessment (HLSA) that can identify potential failure conditions resulting from exposure to the aircraft HIRF and lightning environments. The failure conditions, failure conditions classifications, and independence principles identified by Aircraft Functional Hazard Assessment (AFHA), Preliminary Aircraft Safety Assessment (PASA), System Functional Hazard Assessment (SFHA), and Preliminary System Safety Assessment (PSSA), and lessons learned from previous experience, are used to identify proposed requirements during the development process. Ultimately, these requirements will result in a design capable of demonstrating that exposure to the HIRF and lightning environments will not result in adverse effects to the operation of the aircraft. This document provides guidance for conducting the HLSA process to classify the system and its equipment to the appropriate HIRF and Lightning Certification Levels (HLCLs).

This document and the EUROCAE equivalent, ED-107, provides detailed information, guidance, and methods in support of the Federal Aviation Administration (FAA) Advisory Circular (AC) 20-158 and to the European Union Aviation Safety Agency (EASA) AMC 20-158. AC 20-158 provides a means, but not the only means, for demonstrating compliance with Title 14 of the Code of Federal Regulations (14 CFR) 23.1308 (Amendment 57 and lower), 23.2520 (Amendment 64 and higher), 25.1317, 27.1317, 29.1317, and applicable FAA HIRF special conditions addressing HIRF Protection. AMC 20-158 is applicable to Certification Specifications CS 23.1308 (Amendment 4 and lower), 23.2520 (Amendment 5 and higher), 25.1317, 27.1317, and 29.1317. It should be noted that this document is neither mandatory nor regulatory in nature and does not constitute a regulation or legal interpretation of the regulation. Therefore, an applicant may elect to establish an alternative method of compliance that is acceptable to the certifying airworthiness authorities. The information in this guide represents a collection of the best engineering practices that have been used to certify aircraft HIRF protection. It provides: Practical design considerations HIRF compliance steps Aircraft level verification and testing guidance Detailed guidance for Level A system compliance and testing Detailed guidance for Level B and C system compliance and testing Guidance in the area of continued airworthiness This document provides guidelines for testing the aircraft and equipment for HIRF compliance, with the latter using RTCA DO-160/EUROCAE ED-14 Section 20. This document also contains guidance applicable to both new applications for aircraft certification and historic information applicable to continued compliance with existing aircraft certifications. When establishing continued compliance, it is necessary to review the basis on which the original certification was granted to determine the requirements that were in force at that time in all jurisdictions where the certification was granted.
