The IATA Operational Safety Audit (IOSA) is a global industry standard for airline operational safety auditing. For two decades, IOSA has become the industry benchmark in safety auditing, contributing to improving safety performance and providing extensive cost-saving measures for IOSA participating airlines. The program is a condition for IATA membership.

IATA continually develops the IOSA Standards and Recommended Practices (ISARPs), in cooperation with industry partners. IATA is also the custodian of the IOSA Audit Reports, and manages the IOSA Registry.
