ASTM F3230-21a

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F3230 − 21 F3230 − 21a
Standard Practice for
Safety Assessment of Systems and Equipment in Small
1
Aircraft
This standard is issued under the fixed designation F3230; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This practice covers internationally accepted methods for conducting safety assessments of systems and equipment for “small”
aircraft.
1.2 The applicant for a design approval must seek the individual guidance of their respective civil aviation authority (CAA) body
concerning the use of this practice as part of a certification plan. For information on which CAA regulatory bodies have accepted
this practice (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 inch-pound units are to be regarded as standard. No other units of measurement are included in this
standard.
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.
2. Referenced Documents
2.1 Following is a list of external standards referenced throughout this practice; the earliest revision acceptable for use is indicated.
In all cases later document revisions are acceptable if shown to be equivalent to the listed revision, or if otherwise formally
