Full title and description

SAE ARP6823: Electronic Transactions for Aerospace Systems: An Overview — an SAE Aerospace Recommended Practice that provides a foundational overview of processes, technologies, use-cases and considerations for implementing electronic transactions and digital data exchanges across aerospace systems and supply chains.

Abstract

This recommended practice (ARP6823) outlines the key processes being transformed by digitalization in the aerospace industry and surveys technologies, architectural approaches, and common use-cases for electronic transactions. It was developed by the SAE committee addressing electronic transactions for aerospace (G‑31) and is intended as a “cornerstone” overview to guide standards development and industry adoption of interoperable, traceable, and secure digital information exchanges across design, certification, maintenance, supply chain and operations.

Scope

Provides an overview of technologies and processes relevant to electronic transaction implementation in aerospace. Topics include the types of data and transactions common to commercial aviation (for example certification records, parts provenance, maintenance records and incident investigation data), architectural considerations for digital threads and digital twins, data integrity, provenance, traceability, security concerns, and illustrative use-cases showing how electronic transactions can improve interoperability across OEMs, suppliers, operators and regulators. The document is intended to be broadly applicable across aerospace domains and to inform subsequent standards work by the G‑31 committee.

Key topics and requirements

• Overview of electronic transaction types and stakeholders (OEMs, suppliers, MROs, regulators, operators).
• Data life‑cycle concepts: creation, exchange, storage, provenance, and archival of aerospace data.
• Principles for data integrity, traceability and non‑repudiation in aerospace transactions.
• Architectural approaches and enabling technologies (digital thread/digital twin concepts, structured data formats, APIs, distributed ledgers and other provenance mechanisms).
• Security, access control and authorization considerations for shared aerospace data.
• Illustrative use-cases: certification and continuing airworthiness data, parts tracking and provenance, vehicle health management (VHM) and maintenance records, incident investigation data exchange.
• Interoperability and scalability considerations for multi‑party, cross‑enterprise transactions.
• Recommendations for future standards development and areas for committee focus (gap identification, candidate specifications, and validation approaches).

Typical use and users

Used as an informational/overview reference by aerospace engineers, program managers, data architects, digital transformation teams, procurement and supply‑chain professionals, MRO organizations, regulators and standards developers. Typical uses include scoping digital transaction initiatives, identifying candidate technologies and standards gaps, informing procurement and integration strategies, and guiding internal policy development for data governance and traceability.

Related standards

Related SAE documents and other standards relevant to digital data, digital thread and aerospace information exchange include other SAE ARPs and AIR documents addressing digital data standards, blockchain/digital provenance studies, vehicle health management and lifecycle data (for example related SAE ARP and AIR publications produced by G‑31 and allied committees). Organizations implementing ARP6823 will often refer to other SAE ARPs, industry guidance on digital thread/digital twin, and applicable regulatory guidance on continued airworthiness data.
