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.
The total accident rate for IOSA carriers in 2013 was 2.5 times lower than the rate for non-IOSA operators. As such, IOSA has become a global standard, recognized well beyond IATA membership.
