ARP4761, Guidelines for Conducting the Safety Assessment Process on Civil Aircraft, Systems, and Equipment is an Aerospace Recommended Practice from SAE International.[1] In conjunction with ARP4754, ARP4761 is used to demonstrate compliance with 14 CFR 25.1309 in the U.S. Federal Aviation Administration (FAA) airworthiness regulations for transport category aircraft, and also harmonized international airworthiness regulations such as European Aviation Safety Agency (EASA) CS–25.1309.
This Recommended Practice defines a process for using common modeling techniques to assess the safety of a system being put together. The first 30 pages of the document covers that process. The next 140 pages give an overview of the modeling techniques and how they should be applied. The last 160 pages give an example of the process in action.
Some of the methods covered:
Functional Hazard Assessment (FHA)
Preliminary System Safety Assessment (PSSA)
System Safety Assessment (SSA)
Fault Tree Analysis (FTA)
Failure Mode and Effects Analysis (FMEA)
Failure Modes and Effects Summary (FMES)
Common Cause Analysis (CCA), consisting of:
Zonal Safety Analysis (ZSA)
Particular Risks Analysis (PRA)
Common Mode Analysis (CMA)
