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. All IATA members are IOSA registered and must remain registered to maintain IATA membership.

Benefits for airlines and regulators

IATA Operational Safety Audit (IOSA)
  • 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 organizations with formally trained and qualified auditors
  • Accredited training organizations with auditor training courses

The total accident rate for IOSA carriers in 2012 was 77% lower than the rate for non-IOSA operators. As such, IOSA has become a global standard, recognized well beyond IATA membership. As of 1 May 2013, 138 (37%) of the 381 airlines on the IOSA registry were non-IATA member airlines.
