General Vision Eligibility Schedule your audit Documentation

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. All IATA members are IOSA registered and must remain registered to maintain IATA membership. See who is already on the IOSA Registry


Benefits for airlines and regulators

  • Quality audit program under stewardship of IATA
  • Continuous updating of standards to reflect regulatory revisions and best practices
  • Elimination of audit redundancy, reducing costs and audit resource requirements 
  • Accredited audit org​anizations with formally trained and qualified auditors
  • Accredited training organizations with auditor training courses
  • Structured audit methodology, standardized checklists 


The total accident rate for IOSA carriers between 2011 and 2015 was 3.3 times lower than the rate for non-IOSA operators. As such, IOSA has become a global standard, recognized well beyond IATA membership. As of March 2015, 145 (36%) of the 405 airlines on the IOSA registry were non-IATA member airlines.
