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.

IATA is working to ensure the IOSA Program continues to meet industry needs during the COVID-19 crisis.
The IOSA Support Program (link) provides operators, due for an IOSA renewal registration audit, who are unable to undergo an onsite audit with the possibility of undergoing a remote audit with a limited scope and reduced fees. The rules related with this option are found in the IPM Ed 12 – Temporary Appendix (TA)
This TA also formalizes the requirement for all IOSA registered operators to submit the IOSA questionnaire (SAR.F23 form) every 60 calendar days. See our guidance on how register, access and complete the form. The completed questionnaires can be requested in the same way as for IOSA Audit Reports.
Relevant documents, such as Operator Alerts and Temporary Revisions to the IOSA manuals are available in our documentation site. Subscrib to receive notifications when a new document has been released. For questions or comments, contact us at email@example.com.

IOSA has become a global standard, recognized well beyond IATA membership. As of June 2020, 139 (32%) of the 437 airlines on the IOSA Registry are non-IATA member airlines.

The IOSA Standards and Recommended Practices (ISARPs), as published in the ISM, are applicable only to an operator that operates a minimum (i.e. one or more) two-pilot, multi-engine aircraft that have a maximum certificated takeoff mass in excess of 5,700 kg (12,566 lb) for the conduct of:
- Commercial passenger flights with or without cabin crew
- Commercial cargo flights with or without the carriage of supernumeraries or cargo attendants
ISARPs may not be applied or used for the Audit of an operator that
- Does not operate a minimum of one aircraft as specified above, or
- Has all aircraft operations conducted by another operator.
ISARPs are currently not suitable for and may not be used for the audit of
- Aircraft that have a maximum certificated takeoff mass of 5,700 kg (12,566 lb) or less
- Single engine aircraft operations
- Single pilot aircraft operations
- Helicopter operations
- Seaplane operations
During an audit, ISARPs are applied only to those aircraft that are of the type authorized in the Air Operator Certificate (AOC) and utilized in commercial passenger and/or cargo operations. Other owned or leased aircraft that are not of the type authorized in the AOC and/or not utilized in commercial air transport operations, will not be evaluated during an audit as they are considered outside the scope of IOSA. However, the existence of such aircraft will be referenced with an explanation in the IOSA Audit Report.
