ASTM F3364-23

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: F3364 − 19 F3364 − 23
Standard Practice for
Independent Audit Program for Unmanned Aircraft
Operators
This standard is issued under the fixed designation F3364; 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 establishes a minimum set of requirements for an Unmanned Aircraft Systems (UAS) Operator Independent
Audit Program in compliance with Practice F3365. This document has been purposefully designed within the broader context of
the Committee F38 library. Although the original source materials for the content presented here were intended to function as
standalone documents, the committee has consciously removed any redundant information in favor of adopting a referential
"single-source-of-truth" approach. Consequently, when applying this standard, it is essential to consider and integrate all relevant
Committee F38 standards to ensure its comprehensive and accurate implementation.
1.2 When intending to utilize the information provided in this document as a Means of Compliance for operational or design
approval, or both, it is crucial to consult with the respective oversight authority (for example, CAA) regarding its acceptable use
and application. To find out which oversight authorities have accepted this standard (in whole or in part) as an acceptable Means
of Compliance to their regulatory requirements (hereinafter "the Rules"), please refer to the Committee F38 webpage
(www.ASTM.org/COMMITTEE/F38.htm).
1.3 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.
1.4 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.

3. Terminology
3.1 Unique and Common Terminology—Terminology used in multiple standards is defined in Terminology F3341, UAS
Terminology Standard, and Terminology F3060, Aircraft Terminology Standard. Terminology that is unique to this specification
is defined in this section.
3.2 Definitions:
3.2.1 audit finding, n—a statement of audited entity conditions at the time of the audit by evaluation against audit criteria. Audit
findings shall be based upon verifiable audit data and may be either positive or negative with respect to audit criteria.
3.2.2 independent audit, n—an audit of an unmanned aircraft systems operator and its associate facilities by an external auditing
entity to determine compliance with Civil Aviation Authority (CAA) accepted consensus standards, and procedures established to
meet those requirements.
3.2.3 noncompliant finding, n—a non-fulfillment of a requirement that may affect the ability of the UAS Operator to comply with
the provisions for compliance of the relevant CAA.
4. Significance and Use
4.1 This practice establishes the minimum set of requirements for an independent audit program for unmanned aircraft system
operators. The intended use is to provide minimum requirements for an initial assessment of operators bringing a new aircraft
model or service to market, or for periodic review of an existing operator’s operations.
4.2 Compliance to this practice would ensure that the audit program and those who execute it meet the consensus set of minimum
requirements and qualifications.
4.3 This practice does not mandate operator independent audits.
4.4 Independent audits are to be conducted only at the request of the operator or the relevant CAA. This does not preclude an
independent audit at the request of a court of law or arbitrator.
5. Audit Criteria
5.1 Initial Assessment—When performing an initial assessment audit of an unmanned aircraft system operator, the auditor(s) shall
review compliance to the consensus standards for the aircraft being produced.
5.1.1 The auditing entity shall verify that the referenced consensus standards are appropriate and accepted by the relevant CAA.
5.1.2 At a minimum, the auditor(s) shall assess compliance to the following processes as applicable to the category of aircraft
being produced:
5.1.2.1 UAS Design and Performance;
5.1.2.2 UAS Operating Instructions;
5.1.2.3 UAS Maintenance and Inspection Procedures;
5.1.2.4 UAS Flight Training Supplement (as applicable);
5.1.2.5 UAS Operator’s Quality Assurance System;
5.1.2.6 UAS Operator’s Continued Operational Safety Program; and
5.1.
