IATA Operational Safety Audit (IOSA)

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 6400 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.

The next IOSA Workshop for Airlines will be taking place in Madrid this coming December.
For details and registration, please visit the IOSA Workshop page.

ISM Temporary Revisions for ISM Ed 13 have been published and they will become effective on 1 September 2019.  Find them in our Documentation Site.
