ASTM F2352-14 (2022) PDF

Full title and description

Standard Specification for Design and Performance of Light Sport Gyroplane Aircraft — ASTM F2352‑14 (reapproved 2022). This specification establishes design, construction, performance, flight, and equipment requirements for light sport gyroplane (autogyro/gyroplane) aircraft to support safe manufacture and operation.

Abstract

ASTM F2352‑14(2022) provides requirements and test/verification guidance for designers, manufacturers and maintainers of light sport gyroplane aircraft. Topics include structural design and loads, rotor and control systems, powerplant compatibility, flight performance (takeoff, climb, glide), ground‑handling, cockpit and instrumentation, weight & balance, operating limitations, marking/POH requirements, and supporting documentation such as maintenance manuals. The 2014 edition was reapproved/issued in 2022 as the current edition (F2352‑14R22).

Scope

This specification applies to the design and manufacture of light sport gyroplanes intended for day VFR operation (as defined by relevant national regulations). It addresses structural and flight‑performance requirements, rotor and control systems, powerplant installation and compatibility, equipment and instrumentation, marking and pilot information (POH), and maintenance documentation and procedures necessary to show compliance with the standard’s design and safety criteria. The specification is maintained by ASTM Committee F37 (Light Sport Aircraft) and references related ASTM practices and specifications for engines, maintenance manuals, and quality systems.

Key topics and requirements

• Definitions and terminology specific to gyroplanes and light sport aircraft.
• Flight requirements (takeoff, climb, glide, controllability and maneuverability, performance envelopes).
• Structural loads, material and fabrication requirements, factors of safety, fatigue considerations.
• Rotor system and control system design, rotor blade clearance, rotor head bearings, and rotor/propeller compatibility.
• Powerplant installation, engine compatibility, cooling, fuel and oil systems, propeller clearances and limitations.
• Ground‑handling characteristics, emergency landing conditions, and cockpit design/ergonomics.
• Required documentation: Pilot Operating Handbook (POH), maintenance manual, markings and placards, and quality/production system references.

Typical use and users

Primary users are gyroplane designers and manufacturers, certification and airworthiness authorities, test houses, maintenance organizations, flight training providers and advanced amateur builders working within the light sport category. The standard is also used by component suppliers (engines, rotors, instrumentation) and by operators to verify that a gyroplane’s design and documentation meet recognized industry criteria.

Related standards

F2352 references and is used alongside other ASTM and industry documents addressing engines, maintenance and quality systems for light sport aircraft, for example ASTM F2339 (engine design/manufacture practice), ASTM F2483 (maintenance/manual practices), and ASTM F2972 (manufacturer quality assurance systems), among others listed in the standard. It also aligns with relevant national aviation regulations and certification practices for light rotorcraft.

FAQ

Q: What is this standard?

A: ASTM F2352‑14(2022) is the ASTM standard specification that defines design, performance, and documentation requirements for light sport gyroplane aircraft (autogyros), issued originally in 2014 and reapproved/maintained in 2022.

Q: What does it cover?

A: It covers structural design and loads, rotor and control systems, powerplant and propeller compatibility, flight performance requirements, ground handling, cockpit design and instrumentation, required markings and pilot information (POH), and maintenance/manual requirements to demonstrate compliance.

Q: Who typically uses it?

A: Designers, manufacturers, component suppliers, maintenance organizations, test laboratories, certification/airworthiness bodies, and experienced builders/operators in the light sport gyroplane community.

Q: Is it current or superseded?

A: The 2014 edition (F2352‑14) was reapproved/recorded in 2022 (designation commonly shown as F2352‑14R22 or F2352‑14(2022)); it remains the current ASTM specification unless a newer revision is published after 2022. Check ASTM or committee publications for any post‑2022 revisions.

Q: Is it part of a series?

A: It is maintained by ASTM Committee F37 (Light Sport Aircraft) and is part of a family of ASTM documents addressing light sport aircraft topics (engines, maintenance, manufacturer QA). It cross‑references several related ASTM practices and specifications.
