Full title and description
ASTM F2245 — Standard Specification for Design and Performance of a Light Sport Airplane. This standard establishes airworthiness, structural, performance and equipment requirements for the design and evaluation of powered, fixed‑wing light sport airplanes (LSA) intended for day VFR operation and related certification/design activities.
Abstract
This specification defines minimum design and performance criteria for light sport airplanes, including load and structural requirements, flight performance (stall, takeoff, climb, landing and maneuvering), control and stability, vibration and ground handling, equipment and instrumentation, and required documentation such as a Pilot Operating Handbook (POH). It is intended to support designers, manufacturers and regulators in demonstrating compliance with accepted LSA design practices.
General information
- Status: Active (current edition published 2023; designation F2245-23).
- Publication date: Current edition approved/updated in 2023 (F2245-23; ASTM webstore shows last update Aug 8, 2023). As of February 22, 2026, there is no F2245-26 edition published.
- Publisher: ASTM International (Committee F37 — Light Sport Aircraft).
- ICS / categories: Aircraft and space vehicles in general — ICS 49.020 (airworthiness and aircraft design).
- Edition / version: F2245-23 (most recent published edition).
- Number of pages: Approximately 34–35 pages (sources list 34 pages in one record and 35 in ASTM store).
Scope
The standard applies to the design of powered fixed‑wing light sport airplanes and addresses the airworthiness requirements necessary to demonstrate acceptable structural performance, controllability, maneuverability, stability, vibration characteristics, ground handling and required installed equipment for safe VFR day operation. It is intended for use by designers and manufacturers to develop LSA that meet commonly accepted performance and safety levels and to support regulatory review.
Key topics and requirements
- Design load cases and structural strength requirements for primary and control surfaces.
- Flight performance criteria: stall speed, takeoff, climb, landing, and balked landing conditions.
- Control, stability and maneuverability requirements including envelope and handling qualities.
- Vibration and aeroelastic considerations to ensure safe operation and fatigue life.
- Minimum instrumentation, safety equipment and required placards/documentation (POH content and limits).
- Ground and water (if applicable) load conditions, emergency landing considerations and systems integration guidance.
- Testing, analysis and documentation practices to demonstrate compliance.
Typical use and users
Primary users include light sport airplane designers and manufacturers, conformity assessment bodies, engineering consultants, test laboratories, and regulatory reviewers who use the standard to evaluate design acceptability and prepare technical documentation (for example, Pilot Operating Handbooks). It is also used by flight test teams and quality engineers involved in LSA certification and production oversight.
Related standards
Related guidance and standards include earlier and adjacent revisions of F2245 (for traceability), FAA and EASA advisory material on LSA airworthiness, and other ASTM or international documents referenced within F2245 that cover materials, testing methods and instrumentation requirements. The standard history shows revisions (for example F2245-20) leading to the current F2245-23 edition.
