The IATA Operational Safety Audit (IOSA) Program is an internationally recognized and accepted evaluation system designed to assess the operational management and control systems of an airline.
The IOSA audit creates a standard that is comparable on a world-wide basis, enabling and maximizing the joint use of audit reports. This has saved the industry over 6,400 redundant audits and continues to lead to extensive cost-savings for IOSA participating airlines. All IATA members are IOSA registered and must remain registered to maintain IATA membership.

IOSA and the Risk-Based Approach
In 2024, IOSA transitioned into a risk-based model, focusing on safety risks, specific to the auditee, rather than applying a "one-size-fits-all" approach. IOSA now delivers an audit scope that will be tailored for each airline. Furthermore, the new approach introduces a maturity assessment of the airline's safety-critical systems and programs.
