If a new safety belt is to be installed in an aircraft, it must conform to the strength requirements in which document?

When installing a new safety belt in an aircraft, it is crucial that the belt conforms to the standards set out in Technical Standard Order C22 (TSO C22). This document outlines the specific performance and testing criteria that safety belts must meet to ensure they provide adequate protection in the event of an accident. Compliance with TSO C22 guarantees that the safety belt has been evaluated and meets the federal regulations for strength and reliability.

TSO C22 provides a framework for manufacturers to demonstrate that their products are safe for use in aviation, ensuring that all installed safety equipment complies with federal aviation standards. This is particularly important for occupant safety in aircraft, as these standards address various factors like durability, load resistance, and overall performance during crash scenarios.

While FAA regulations offer a broad overview of safety requirements in aviation, TSO C22 specifically targets the performance of safety belts, making it the relevant document for this particular installation. Other options, such as Airworthiness Directives or PMA Guidelines, pertain to different aspects of aircraft maintenance or modification standards, and while they may reference safety equipment management, they do not provide the specific performance standards that TSO C22 does for safety belts.
