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 Workshop at WSOC
We are excited to invite you to a free IOSA Workshop on 12 October 2025 at the Fairmont Xiamen, China.
This workshop is held in conjunction with IATA's World Safety and Operations Conference (WSOC) from 14-16 October 2025!
The IOSA workshop will be in person, featuring updates on the IOSA program, the latest developments in Risk-Based IOSA (RBI) and more.
Space is limited, so be sure to complete the registration form before it's too late! Once you have registered, you will be placed on a waitlist. You will receive an email from the IOSA team when your space at the workshop is confirmed.
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.
