ASTM F3322-22 PDF

Overview

ASTM F3322-22: Standard Specification for Small Unmanned Aircraft System (sUAS) Parachutes establishes comprehensive requirements for the design, manufacture, and testing of parachute recovery systems (PRS) used on small unmanned aircraft (sUA). The primary goal is to ensure safety by reducing the impact energy in the event of a failure, supporting operators and manufacturers in obtaining approval from civil aviation authorities (CAA) to conduct flights over people.

This standard outlines essential criteria for the integration, construction, functionality, and ongoing maintenance of deployable sUAS parachute systems, facilitating both regulatory compliance and increased operational safety.

Key Topics

• Design & Fabrication Requirements: Defines how parachute systems should be designed and fabricated for optimal integration and performance within the sUA platform.
• Testing Protocols: Specifies comprehensive testing standards, including preflight/postflight inspections, deployment success criteria, and system resilience under various failure scenarios.
• Documentation & Traceability: Requires that all key PRS components are serialized, tracked, and supported by detailed documentation to ensure traceability and accountability throughout the lifecycle.
• Operational Limitations: Sets forth the environmental and technical limitations for safe parachute operation, including wind speed, temperature, altitude, and approved payload configurations.
• Safety Features: Mandates the inclusion of features such as independent power sources, autonomous triggering systems (ATS), and flight termination systems (FTS) to minimize risks to people and property.
• Maintenance & Inspection: Establishes guidelines for regular inspection, maintenance, and repacking to promote continued operational safety and compliance.

Applications

This ASTM parachute specification is especially relevant for:

• sUAS Manufacturers & Integrators: Provides clear requirements and best practices for designing and implementing PRS in new or existing drone platforms.
• Commercial Drone Operators: Supports compliance for operations over people or critical infrastructure by aligning parachute systems with regulatory requirements.
• Regulatory Submissions: Facilitates preparation of documentation needed to obtain TSO, flight certificates, waivers, or permits from civil aviation authorities.
• Safety-Critical Missions: Enhances the safety of drone missions in urban, industrial, or public environments, reducing the potential risk during emergency landings.
• Quality Assurance Programs: Forms a foundation for internal quality control, supplier audits, and third-party verification of drone parachute systems.

Related Standards

Companies and organizations using or specifying ASTM F3322-22 should also consider these related standards for a comprehensive approach to sUAS airworthiness and operational safety:

• ASTM F2908: Specification for Unmanned Aircraft Flight Manual (UFM) for a UAS.
• ASTM F2909: Specification for Continued Airworthiness of Lightweight UAS.
• ASTM F3003: Specification for Quality Assurance of a Small Unmanned Aircraft System (sUAS).
• ASTM F3364: Practice for Independent Audit Program for Unmanned Aircraft Operators.
• 14 CFR Part 107: Federal Aviation Administration (FAA) regulations for small unmanned aircraft systems.
• MIL-STD-1629A: Procedures for Failure Mode, Effects, and Criticality Analysis (where applicable to components of the parachute system).

These standards, when used in conjunction, contribute to a robust framework for ensuring the design, quality, and regulatory compliance of both the aircraft and its safety systems.
