ASTM F3232/F3232M-23
(Specification)Standard Specification for Flight Controls in Small Aircraft
Standard Specification for Flight Controls in Small Aircraft
ABSTRACT
This specification applies to the flight control aspects of airworthiness and design for "small" aircraft. It establishes the Aircraft Type Code (ATC) compliance matrix based on airworthiness level, number of engines, type of engine(s), stall speed, cruise speed, meteorological conditions, altitude, and maneuvers. An ATC is defined by taking into account both the technical considerations regarding the design of the aircraft and the airworthiness level established based upon risk-based criteria. The requirements established by this specification for manual flight control cover control surface installation, operation and arrangement, control system stops, trim systems, control system locks, limit load static tests, operation tests, control system details, spring devices, cable systems, wing flap controls, wing flap position, and flap interconnection. Requirements for automatic flight control cover automatic pilot systems, stability augmentation, and artificial stall barrier system.
SCOPE
1.1 This specification covers international standards for the flight control aspects of airworthiness and design for “small” aircraft.
1.2 The applicant for a design approval must seek the individual guidance of their respective CAA body concerning the use of this specification as part of a certification plan. For information on which CAA regulatory bodies have accepted this specification (in whole or in part) as a means of compliance to their Small Aircraft Airworthiness regulations (hereinafter referred to as “the Rules”), refer to ASTM F44 webpage (www.ASTM.org/COMMITTEE/F44.htm) which includes CAA website links.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
