SAE ARP5583B

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. With the original release of the document and Revision A, and as experience was gained with these documents, some changes and clarifications were needed to ensure consistent approaches to aircraft and integrated system HIRF tests. Revisions were incorporated to align with AC 20-158/AMC 20-158, ARP5415/EUROCAE ED-158, ARP60493/EUROCAE ED-248, RTCA DO-160/EUROCAE ED-14, CATA paper TCCA-001, obsolescence, test methods, editorial updates, and lessons learned. Additionally, guidance for HIRF safety assessment has been moved to ARP8482/EUROCAE ED-338. Due to the extensive rework and reorganization of this revision, the standard “change bar” indications for the changes are not shown. Therefore, an “R” has been placed before the document title.
