ARP4761, Guidelines for Conducting the Safety Assessment Process on Civil Aircraft, Systems, and Equipment is an Aerospace Recommended Practice from SAE International.

This Recommended Practice defines a process for using common modeling techniques to assess the safety of a system being put together.

FHA results are normally shown in spreadsheet form, with columns identifying function, failure condition, phase of flight, effect, hazard classification, DAL, means of detection, aircrew response, and related information.

Untimely deployment of thrust reverser would be a hazard, which could be assigned an identifier based on ATA code 78-30.

The CCA consists of three separate types of analyses which are designed to uncover hazards not created by a specific subsystem component failure.

The Particular Risk Analysis (PRA) looks for external events which can create a hazard such as a birdstrike or engine turbine burst.

Cutset analysis of the fault trees demonstrates that no single failure condition will result in a hazardous or catastrophic event.

The SSA summarizes the residual risks remaining in the system and should show all hazards meet the 1309 failure rates.

The ARP4761 analyses also feed into Crew Alerting System (CAS) message selection and the development of critical maintenance tasks under ATA MSG3.
